| 摘 要： | 目的 制备改性的壳聚糖(CTS),对其吸附氯酚的性能进行研究.方法 通过戊二醛作为交联荆将壳聚糖进行改性,用红外光谱(FTIR)对改性后的壳聚糖进行了表征.考察了吸附时间、溶液pH值、氯酚浓度等因素对吸附的影响.结果 改性CTS具有较好的抗酸碱性能;在pH6.5、吸附40min时对氯酚的吸附量最大;改性后的CTS吸附能力增加了13.8倍;且能再生和重复使用.结论 经戊二醛交联后的壳聚糖是良好的氯酚吸附剂.

| Abstract: | Objective To study the adsorption of 2,4-dichlorophenol of the modified chitosan.Methods A type of N-alkyl chitosan derivative was synthesized by using glutaraldehyde as a kind of crosslinker and characterized by FTIR.The effects of adsorption conditions,such as time,pH,the concentration of 2,4-dichlorophenol and the amount of the modified chitosan on the adsorption quantity of 2,4-dichlorophenol adsorpted were studied.Results The resistance on acid and alkaline of N-alkyl chitosan exhibited was good acid r... |
