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 SF(Cd/Ca) of PPM40-NH₂ was 3-7 fold higher than that of PPM40 although the C(Ca) was 100-1000 times higher than that of C(Cd). The chelating effect of -COOH and -NH₂ in PPM40-NH₂ corresponded well with the selective adsorption of Cd(II), as confirmed by simulations....
