8-羟基喹哪啶树脂对Pb^(2+)的吸附性能

Adsorption Properties of 8-Hydroxyquinaldine Resin on Lead Ion

用静态法研究了含8-羟基喹哪啶功能基的新螯合树脂对铅离子的吸附性能,实验发现,该树脂对微量Pb2+有着良好的吸附特性。实验结果表明,在pH4.0时,静态饱和吸附容量为5.02 mg/g树脂,一次洗脱回收率达96.56%。吸附过程符合Langmuir和Freundlich模型。

Adsorption of the new chelating resin, 8-hydroxyquinaldine resin on lead ion was studied by static method, and the result showed that the resin had good absorption on lead ion, with static saturated adsorption of 5.02 mg/g resin and the elution recovery of 96.56% at the first time. The adsorption process was accorded with Langmuir and Freundlich models.
