| 摘 要： | 用对羟基苯甲醛、水杨醛和香草醛对壳聚糖进行了修饰.探讨了产物对微量Hg2+,Pb2+,Au3+,Cu2+,Ag+,Cr3+,Cd2+,Ni2+和Zn2+的吸附性能.结果表明,改性后的壳聚糖具有不易流失、易再生的特点,并且对离子的去除率较高,尤其对Hg2+,Pb2+和Au3+,去除率更高.

| Abstract: | Chitosan was modified by p-hydroxybenzaldehyde,salicylaldehyde and vanillin via Schiff reaction and the resulting products were investigated in relation to its adsorption behavior for low concentration metal ions Hg~(2+),Pb~(2+),Au~(3+),Cu~(2+),Ag~(+),Cr~(3+),Cd~(2+),Ni~(2+) and Zn~(2+).The resultsindicated that the modified chitosan had good properties∶hard to be run off, easy to be regenerated and high percentage of removing metal ions,especiallyfor Hg~(2+),Pb~(2+)和Au~(3+)ions. |
