1511	Tin Tin Sein	PREPARATION AND APPLICATION OF ORGANIC FERTILIZERS FROM VEGETABLE WASTES, COW DUNG, SESAME MEAL CAKE AND EFFECTIVE MICROORGANISM SOLUTIONS	Organic fertilizers were prepared from the selected materials such as wastes of vegetables, cow dung, sesame meal cake, rice straw and the prepared EM solution under aerobic and anaerobic conditions. To know the effect of lime on the prepared fertilizers, quick lime powder was used. The aerobic digesters (4' � 6'� 0.75') were used in aerobic conditions. The anaerobic digesters (11.5? � 13.5?) were used in anaerobic conditions. The successive layers of selected materials were done and prepared EM solution was added over the layers. Organic fertilizers were performed by composting. The elemental contents of prepared organic fertilizers were determined by Energy Dispersive X-Ray Fluorescence (EDXRF) spectroscopic method. The physical properties, the moisture contents and pH values of prepared organic fertilizers were determined. The total nitrogen, total phosphorus and total potassium contents of the prepared organic fertilizers were determined by instrumental methods. The amount of organic carbon and organic matter of the prepared organic fertilizers were also determined. The properties of prepared aerobic organic fertilizers were compared with anaerobic organic fertilizers. To show the effect of the prepared organic fertilizers, the plantations on those of vegetables such as Chinese cabbage, lettuce and radish were carried out by using four kinds of prepared organic fertilizers and the plant growth was compared.	2021
1512	Chit Chit Maw	SYNTHESIS AND CHARACTERIZATION OF FULLERENE FROM GRAPHITE ORE	This research work concerned with synthesis and characterization of fullerene from graphite ore. The graphite ore was collected from Thabeikkyin Township, Mandalay Region. The synthesis of fullerene was carried out by Modified Hummer�s method in which graphite powder was oxidized with the help of oxidizing agent H2SO4 and KMnO4. Moreover, the various amounts of NaNO3, H3PO4, KMnO4 and H2SO4 were used to produce fullerene. The crystal lattice size of graphite and fullerene were characterized by X-ray diffraction (XRD). The prepared fullerenes were analysed by Thermo gravimetric analysis (TG-DTA). The morphology of the graphite and the synthesized fullerene were investigated by scanning electron microscope (SEM).	2021
1513	Htet Htet Than Sein	PREPARATION AND CHARACTERIZATION OF CARBOXYMETHYL CELLULOSE (CMC) FROM PINEAPPLE LEAVES	Pineapple leaves are one of the abundantly available waste materials and used for production natural fibres. Cellulose was isolated from pineapple leaf fibres (PALF) by mechanical and chemical treatments using alkaline, inorganic salts and acids. Cellulose was then converted to carboxymethyl cellulose by an alkalization and etherification process, using various concentrations of sodium hydroxide (10 %, 20 %, 30 % and 40 % w/v) and sodium monochloroacetate (SMCA), in isopropyl alcohol medium. All the carboxymethyl cellulose (CMC) obtained from various concentrations of NaOH were investigated on yield percent, solubility of water and degree of substitution to get the optimum CMC. These results indicate that the optimum reaction of alkalization was reached at 30 % NaOH. The physicochemical properties of optimum CMC such as moisture content, pH and solubility were also determined. Characterization of raw sample, bleached sample, cellulose and CMC were carried out by analyzing the XRD pattern, spectra of FT IR and SEM photomicrographs. The XRD analysis showed that the native cellulose was transformed into an amorphous phase, as evidenced from the characteristic peaks that had almost disappeared. FT IR analysis indicated that, in addition to the main characteristic bands of cellulose, CMC showed new characteristric absorption bands at 1591 and 1413 cm-1 , which are associated with the anti-symmetric and symmetric stretching vibrations of COO- , respectively. In SEM analysis, it can be seen the significantly changes from cellulose to CMC. These results confirmed the carboxymethylation process from cellulose.	2021
1514	Thandar	USING SLOW SAND FILTRATION METHOD WITH DOMESTIC CHARCOAL TO TREAT DISTILLERY WASTEWATER IN AUNGLAN TOWNSHIP	Distilleries generate large volume of wastewater which poses a considerable environmental impact by polluting the natural environment. This study focused to evaluate the feasibility of slow sand filtration integrated with domestic charcoal layer as a promising treatment method for the distillery wastewater effluent. Distillery wastewater was collected from Aunglan Township, Thayet District in Magway Region. Before and after treatment for two weeks, selected parameters of effluent were analyzed. All of the effluent parameters (pH, conductivity, total alkalinity, COD, DO, BOD, and chloride, calcium, magnesium and bicarbonate) of treated distillery wastewater sample were within the allowable limits of USEPA standard except turbidity, total hardness, TDS, total phosphate, ammonia nitrogen. After treatment, pH value of the acidic wastewater changed from 3.67 to 6.10 and total alkalinity and total hardness values were found to be 70 ppm and 550 ppm, respectively. E.coli in the distillery wastewater was reduced significantly than the initial value but higher than USEPA limit. The slower sand filtration treatment can be taken as an alternative and economical method for treatment of wastewater.	2021
1515	San San Kyu	INVESTIGATION ON CONTAMINATION OF HEAVY METALS IN ROADSIDE SOIL AT KALI-TOLLGATE AND BAYINTNAUNGQUARTER BETWEEN BAGO-MAWLAMYINE HIGHWAY	The research work intend to study the heavy metal contamination, originating from motor vehicle traffic in roadside soils near the Kali-Tollgate and Bayintnaung- Quarter on the highway road of Bago to Mawlamyine. Twenty one soil samples were collected from (Kali-Tollgate) according to the distances. Five soil samples were collected from Bayintnaung-Quarter according to the depth profile. Semi-quantitative analyses of the soil samples were done using EDXRF technique. Atomic absorption spectrophotometric method was used for the determinations of heavy metals in soil samples. Changes of concentrations of heavy metals (Pb, Zn, Cu and Cd) with distance from the highway road were studied by using single exponential decay model equation. The data were compared with maximum allowable limit of soil of highway road. The Lead content of the roadside soil range from 12.1 to 102.5 ppm, the Zinc content of the roadside soil range from 8.8 to 206.5 ppm, the copper content of the roadside soil range from 14.1 to 111.5 ppm and the cadmium content of the roadside soil range from 1.3 to 7.9 ppm according to the distance. In general heavy metal concentration decreased with increased distance from the highway road. In all soil samples measured according to the depth profile, Zn concentration was highest, whereas Cd concentration was lowest. In the depth profile of 0.5, 20- 30 cm, Pb concentration were in the range of 55.10 ppm to 20 ppm, Zn concentration were in the range of 264.20 to 56.60 ppm ,Cu concentrations were in the range of 48.0 ppm to 9.2 ppm, Cd concentrations were in the range of 2.1 ppm 1.3ppm. The maximum heavy metal concentration was observed at 0-5 cm depth and the concentration decreased with an increase. The data obtained that measured according to the distances except Cd, were within the maximum allowable limit. They slowly find entry into food chain leading to serious health hazards. Therefore, there is an urgent need for policy regulations to minimize indiscriminate disposal of oil contaminated residues, vehicular emissions, road transport and traffic emissions and the wear and tear of mechanical parts in vehicles beside.	2021
1516	Nwe Nwe Win	AN INVESTIGATION INTO THE EFFICACY OF GRAPHENE OXIDES AS AN ADSORBENT FOR THE REMOVAL OF LEAD FROM AQUEOUS SOLUTION	Heavy metals are a concern in the environment as they accumulate and are non-biodegradable and thus bio-toxic. Many technologies have been employed for the removal of heavy metals in the environment. However, adsorption process is arguably the most promising and effective fundamental approach for the removal of heavy metals in wastewater treatment processes. An effective and facial method for removal of Pb2+ ion from aqueous solution is based on the prepared graphene oxides. The oxygenous functional groups on the surface of graphene oxides were primarily responsible for the sorption of metal ions. The graphene oxides were prepared from different graphite sources using modified Hummer�s method. The prepared graphene oxides (LGO, CGO, FGO) were used as adsorbent for removal of heavy metal ion (Pb2+ ion). The different graphite varieties (LGP, CGP, FGP) and the prepared graphene oxides (LGO, CGO, FGO) were characterized by XRD, UV-vis, FT IR and SEM. To obtain the optimum parameters for the removal of Pb2+ ion from model aqueous solution, adsorbent dosage, Pb2+ ion concentration and contact time were examined by complexometric titration method. The maximum removal capacity of Pb2+ ion using LGO, CGO and FGO were found to be 94.60 %, 95.66 % and 87.32 % at their optimal conditions. The removal capacity of Pb2+ ion on CGO and LGO was not quite different but FGO was lower than the other two. The obtained results demonstrated that the prepared graphene oxides can be used as an effective adsorbent for Pb2+ ion removal from water.	2021
