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.
