摘要：
An amino-functionalized water-retaining agent (PPM40-NH2) and a water-retaining agent lacking functionalization (PPM40) were prepared to investigate their selective Cd(II) removal properties. The affinity for Cd(II) was increased after introducing the amino functional group.
The SFCd/Ca of PPM40-NH2 was 3–7 fold higher than that of PPM40 although the CCa was 100–1000 times higher than that of CCd. The chelating effect of –COOH and –NH2 in PPM40-NH2 corresponded
well with the selective adsorption of Cd(II), as confirmed by simulations. A s...
