1,4-双-(二硫代羧基)哌嗪乙基聚合物的合成及其吸附性能
摘要:
采用低温固相反应合成了1,4-双-(二硫代羧基)哌嗪乙基聚合物,用它作为吸附剂对废水中的重金属离子和苯胺进行了吸附和解吸性能测试。结果表明,聚合物能够定量的吸附重金属离子,对Ag+、Pd2+有较高的吸附容量,吸附率分别达到98.2%和95.4%;对初始质量浓度为500 mg/L的苯胺废水进行一次性处理,苯胺质量浓度降低为10 mg/L左右,吸附剂具有优良的再生性能,可以反复使用。

Synthesis and Adsorption Property of Polyethylene-1,4-dithio-carboxyl piperazine
Abstract:
Polyethylene-1,4-dithio-carboxyl piperazine(Pzdtc) was prepared in solid state at temperature below 10℃ and characterized. Its sorption and desorption properties towards a series of heavy metal ions and aniline in waste water were examined. The results showed that the polymer could adsorb heavy metal ions in certain amount. Its adsorption capacity for Ag+ and Pd2+ was 98.2% and 95.4%, respectively. The concentration of aniline in waste water could be reduced from 500 mg/L to about 10 mg/L after treatment by the polymer. The polymeric adsorbent could be reused repeatedly after regeneration.
