Abstract考察了聚(丙烯酸—co—丙烯酰胺)/凹凸棒黏土高吸水性树脂吸附剂(标记为Super-Ⅰ)对重金属Pb2+的吸附行为及溶液pH(3.0~7.0)、吸附时间(0~720 m in)、Pb2+溶液初始浓度(0.002 5~0.03 mol/L)和吸附剂加入量(0.08~0.30 g)等因素对吸附性能的影响。在pH=6.0、吸附时间60 m in、Pb2+溶液初始浓度0.02 mol/L和吸附剂用量0.1 g条件下,该吸附剂对Pb2+的吸附量达到296.0 mg/g。高吸水性树脂吸附剂对Pb2+的吸附行为符合准二级动力学模型和Langmu ir等温线模型。与常用多孔吸附剂相比,该三维网络吸附剂对Pb2+的吸附量高出1~2个数量级。
