摘　　要：用壳聚糖改性天然伊利石制备伊利石负载壳聚糖吸附剂,研究吸附剂对活性红KD-8B染料废水吸附。结果表明,最合适吸附条件为:溶液pH值5,壳聚糖负载量为1.3g,吸附剂量为0.6g。吸附过程动力学方程符合准二级反应动力学模型,吸附等温线用Langmuir方程的拟合效果优于Freundlich方程。Illite load chitosan adsorbent was prepared with chitosan modified nature Illite and its adsorption to reactive red KD- 8B dye wastewater was studied. The result showed that the proper adsorption conditions were： pH 5; Chitosan load 1.3g; the dosage of the adsorbent was 0.6g. The adsorption process followed a perudo-second order equation and the equilibrium isotherm was best described by the Langmuir model rather than the Freundlich model.
