MODIFIED POLYSTYRENE SPHERICAL RESIN AND PROCESS FOR DECONTAMINATING WASTE WATER BY USING THE SAME

摘要

An absorbent, polystyrene spherical resin grafted with polyethylene glycol characterized in that polystyrene resin is crosslinked with 1 to 10 wt.% of devinylbenzene, the content of polyethylene glycol is more than 50 wt.% and the molecular weight of polyethylene glycol part is more than 500 Da, is described. In addition processes for decontaminating dye contained in waste water of dye industry, heavy metal ion contained in waste water, surfactant, humic substance contained in trash sediment effectively and quickly by using the said adsorbent, are disclosed.
