ADSORPTION BEHAVIOUR OF HAZARDOUS ORGANIC SOLUTIONS ONTO NEW POLYMERIC SORBENT

The fate of herbicides in soil, and surface and groundwaters is determined by several factors including retention, transformation, and transport processes. Environmental pollutants removed from waters of these chemicals is important for all biologic life. In this study, adsorption of textile dyestuffs or adsorption of pesticides such as bisphenol A, 4-amino nitrophenol, phenoxyacetic acid were examined on PVBCIm. This polymer was obtained by modifying polyvinyl benzyl chloride (PVBC) resin with imidazole. This method, has been extended to chloro methyl group to preparepoly (N-vinyl imidazole) (PVIm) graft chains on crosslinked polyvinyl benzyl chloride (PVBC) polymer. In the aqueous solution the adsorption of organic waste was determined by UV-vis spectrophotometer. For different concentrations of hazardous organic wastes in aqueous solution, Freundlich, Langmuir, and BET isotherms were applied at 25 oC.
