USING LOW COST WASTE GLASS ADSORBENT FOR METHYL VIOLET REMOVAL FROM WASTE WATER

The objective of this action is concentrated on employ cheap , available and environmentally clean adsorbent such as waste glass which is widely used in our daily life for the removal of methyl violet (MV) 2B from aqueoussolution, that’s resulted from widely number of industries by adsorption process. The characterization for the prepared adsorbent such as X-ray diffraction (XRD), scanning electron microscopy (SEM), BET surface areaand Fourier transform infrared (FTIR) spectroscopy was achieved. The experiments were carried out to measure the adsorption capacity as a function of contact time, initial concentration (20-80mg/L), pH (4-10),adsorbent dose (0.5-10 g/L), contact time (30-180) min, and particle size of the adsorbent (75,150)Mm were studied. Adsorption isotherms were fitted with the Langmuir and Freundlich models were found to be moreexemplified to the experiments with high correlation coefficient. The results showed that the variation of particle size of waste glass powder has a slighteffect on the removal of (MV) and higher percentage of dye removal by using waste glass was observed with particle size of 75 m, pH 4, at room temperatures for 30 min, 10 g adsorbent dose and 60 mg/L initial dye concentration is 98.7%.
