摘要
研究了无机、有机和无机-有机柱撑膨润土对水中苯胺的吸附去除性能,结果表明:3种柱撑膨润对苯胺的去除效果明显高于膨润土原土,当投土量为0.2 g时,对苯胺的吸附去除率分别为86.77%9、6.38%9、2.51%;3种柱撑膨润土对苯胺的吸附在60 min达到平衡;溶液pH值对苯胺的去除有一定的影响,在酸性条件下的去除率略大于中性和碱性;温度升高,苯胺的去除率略有下降。
Studying the removing effect of inorgano- pillared bentonite , organo- pillared bentonite and inorgano- organo - pillared bentonite on aniline from aqueous solution ,the result showed that the adsorption behavior of 3 kinds of pillared bentonites on aniline was much better than raw bentonite. While dropping 0.2 g, 86.77 % ,96.38 % ,92.51% of aniline was adsorbed. The adsorption of aniline reached balance 60 minutes later. Temperature and pH have a little effect on the removal of aniline. There is a little more adsorption in acid condition than alkaline and pH = 7 condition . Higher temperature has a little less adsorption of aniline.
