摘要:
利用有机膨润土中溶液平衡关系和有机碳含量对有机膨润土吸附, 研究了十六烷基三甲基溴化胺(C TMAB)、十二烷基 三甲基溴化铵(DTMA B)、溴化十八烷基三甲铵(OTMAB) 3 种类型表面活性剂在不同用量下对苊、β -萘酚、苯酚和萘的吸 附结果。通过拟合K ow和K oc之间的关系, 在有机污染物Kow和有机膨润土对不同种类表面活性剂交换容量之间建立定量关系 得到污染物去除预测模型。验证表明, 模型对于菲、萘等K ow 较大化合物吸附的预测结果有较好的相关性, 预测偏差较小;对 于K ow 较小的如硝基苯等物质的吸附预测偏差较大
Abstract:
A bsorptio n acenaphthene , β -naphthol , phenol and naphthalene by cety lt rimethy lammonium bromide (C TMAB), dodecylt rimethy lammo nium bromide (DTMAB), octy lt rimethylaluminum bromide (OTMAB)modif ied bento nite in one step at dif ferent dosages were studied .Based on the balance of o rganic pollutio n and o rg anic carbon content of o rganobentoni te adso rption , the mo del w as built by fit ting the relationship of K ow and K oc .The resul ts show ed that the model predicted a bet ter correlatio n for o rganic compo unds w ith hig h K ow like the philippines , naphthalene and other compounds , the e rror w as ignorable ; fo r low Kow substances adso rption such as nit robenzene , the predictive result showed high devia tion .
