摘要
以正戊醇和阳离子表面活性剂十六烷基三甲基溴化铵(HTAB)形成的反胶束体系对甲基橙(MO)的去除效果进行研究。同时分析了反应时间,HTAB浓度、pH值和离子强度及种类对去除率的影响。实验发现,反应时间为5 min即可达到平衡;最佳HTAB浓度为0.5 g/L;碱性环境有利于甲基橙的去除;离子强度过高时严重抑制MO的去除,改变阴离子种类对去除率有显著影响。
The removal of methyl orange （ MO） by reversedmicelle system , which formed by pentanol and cationic surfactant hexadecyl trimethyl ammonium bromide （ HTAB ） was studied.The effect of reaction time , HTAB concentration , pH value and ionic strength and species were analyzed.Results showed that the reaction struck a balance in 5 min, the optimal concentration of HTAB was 0.5 g/L, and a relative high removal efficiency of methyl orange was obtained in alkaline environment.High ionic strength seriously inhibited the removal of MO , and anion species made a remarkable effect on the removal efficiency of MO.
