摘要

Abstract

Polymer-supported hydrous iron oxides (HFOs) are promising for heavy metals removal from aqueous systems. The ubiquitous inorganic ligands

e.g

sulfate

are expected to exert considerable impacts on pollutants removal by these hybrid sorbents. Herein

we obtained a hybrid sorbent HFO-PS by encapsulating nanosized HFO into macroporous polystyrene (PS) resin. Both batch and column sorption experiments of Cu(Ⅱ) by HFO-PS were carried out in the presence of sulfate. Obviously

the presence of sulfate is favorable for Cu(Ⅱ) sorption onto HFO-PS. The performances of column Cu(Ⅱ) removal were fitted and predicted with Adams-Bohart

Clark

Thomas and BDST models. Thomas model is suggested best-fit to predict the breakthrough curves. Besides

a linear correlation is observed between breakthrough time and column length based on BDST model

which might be useful for predicting the breakthrough time for Cu(Ⅱ) removal by HFO-PS.
