摘要：

The adsorption of hexavalent chromium [Cr(VI)] from aqueous solutions using weakly basic ion-exchange resin D301 was studied in this work. The result showed that the adsorption of Cr(VI) was strongly dependent on pH, the optimum condition was investigated at pH 2 and the maximum adsorption capacity was 247.71 mg g(-1). The equilibrium datas were fitted well with Langmuir and Redlich-Peterson isotherm models. The pseudo-second-order rate equation was best represented by the adsorption process.
