聚乙烯吡咯烷酮掺杂聚吡咯对灿烂绿吸附性能的研究
|
摘要
采用原位聚合法制备了聚乙烯吡咯烷酮掺杂的聚吡咯,对聚吡咯的结构进行了表征。研究了聚吡咯作为吸附剂对灿烂绿的吸附性能,探讨了吸附剂用量、温度、时间及灿烂绿起始浓度对吸附效果的影响。在灿烂绿溶液50mL初始浓度为90mg/L,聚吡咯用量为0.10g,吸附时间为90min,温度为25℃条件下,聚吡咯对灿烂绿的吸附量为42.03mg/g。吸附动力学分析表明吸附过程为化学吸附,等温吸附规律符合Freundlich模型。聚吡咯对灿烂绿的吸附是自发过程。
The polypyrrole doped with polyvinyl pyrrolidone was prepared by in-situ polymerization.The structure of polypyrrole was studied.Then the absorption properties of polypyrrole which used as adsorbents on brilliant green were investigated.The effects of adsorbent dosage,temperature and time on the efficiency were examined.Under the conditions of bright green solution volume 50 mL,the initial concentration 90 mg/L,the polypyrrole dosage 0.10 g,the adsorption time 90 min,the temperature 25℃,the adsorption capacity of polypyrrole on bright green was 42.03 mg/g.Adsorption kinetic analysis showed that the adsorption process was chemical adsorption.The isothermal absorption process followed freundlich isotherm,suggesting that polypyrrole absorbed brilliant green was a spontaneous process.
