摘要
通过悬浮聚合的方法,合成了一种聚乙烯吡啶树脂(WH-06)。以大孔弱碱树脂D301和超高交联树脂NDA150作为参照,研究了WH-06树脂对间苯三酚的吸附性能,探讨了溶液的p H及无机盐对树脂吸附间苯三酚的影响。结果表明,WH-06树脂对间苯三酚的吸附等温线都同时满足Langmuir和Freundlich等温吸附方程,且间苯三酚在WH-06树脂上的吸附是一放热过程,能够自发进行,无机盐对WH-06吸附间苯三酚几乎无影响。
Polyvinylpyridine resin( WH-06) was synthesized via suspension polymerization. The adsorption performance of WH-06 to phloroglucinol was studied through static experiments,comparing with the two commercial adsorbents of weak base resin D301 and hypercrosslinked resin NDA150. The effects of p H and inorganic salt in solution were also discussed. Results showed that the adsorption date fitted both the Langmuir and Freundlich adsorption isotherms well. Adsorption of phloroglucinol onto WH-06 was suggested an exothermic process which ran spontaneously,and the inorganic salt laid less influence on the adsorption.
