本文讨论了高交联玉米淀粉与甲基丙烯酸甲酯接枝共聚物(HCS-g-MMANHNH_2)对银的吸附条件,并对电镀废水中的银进行富集测定.测定范围广,变异系数为1.6%,回收率在90%以上.
In this paper, the adsorption conditions of silver on high cross-linked corn starch and methyl methacrylate (HCS-g-MMANHNH_2) were discussed and the determination of silver in electroplating waste water was carried out. The determination range was wide and the coefficient of variation was 1.6%, recovery rate above 90%.
