摘要
本文报道了5-Br-PAN-S螯合形成树脂(简称BPS树脂)的制备,研究了D-290树脂吸附5-Br-PAN-S的机理和BPS树脂对Cu^(2+)的吸附速率以及在15℃和25℃下的等温吸附线。建立了采用BPS树脂富集-AAS测定天然水中Cu^(2+)、Zn^(2+)、Cd^(2+)的方法。
The 5-Br-PAN-S chelating resin was pre pared. The mechanism for the sorption of 5-Br-PAN-S by D-290 resin was investigated. The absorption rate for Cu and isotherm adsorptive curve at 15 and 25℃were found experimentally. A method for determination of Cu, Zn, and Cd in natural water using 5-Br-PAN-S resin by AAS was established.
