摘要
制备了以壳聚糖作为改性剂，与膨润土靠静电引力形成的复合吸附剂，实验了用此复合吸附剂吸附废水中邻苯二酚的最佳条件：当壳聚糖的负载量为0．05mg／g．投加量为2．Og，振荡时间180min，温度25℃，pH为11．0，振荡速率130r／min时，对废水中邻苯二酚的吸附效果最佳，对吸附机理进行了讨论，壳聚糖改性膨润土吸附邻苯二酚的行为符合Freundlich吸附模式。
The composite absorbent is prepared by the chitosan, as modifier, and bentonite, which is formed by static e lectricity, and catechol wastewater is adsorbed by the composite absorbent, it is showed that the adsorption of catechol the best conditions： catechol wastewater depending on the type of chitosan for 0. 05mg/g. dosing quantity to 2.0g, oscillating time 180min, the temperature 25℃, pH value for 11.0, oscillating rate 130r/min. Catecholwastewater is very good adsorption
