摘　　要：研究羟基铁交联累托石的制备及其对Cr^(6+)的吸附性能。当溶液pH值为3左右，羟基铁交联累托石(以下简称CLR)～的用量为13.2g／LH_2O时，常温振荡吸附60min，Cr^(6+)的去除率可达到98％，残留Cr^(6+)浓度可降至0.5mg／L以下。The preparation and the adsorption properties of the hydroxy-ferrum cross-linked rectorite were studied. The result showed that when 13.2g adsorption agent was added in 1L wastewater, the pH of the mixed liquor was about 3, and adsorption time was 60 min, the removal rate of Cr^(6+) was above 98% and the concentration of the remaining Cr^(6+) was lower than 0.5 mg/L.
