Gongye shui chuli, 2008 用磷酸三丁酯(TBP)为萃取剂和煤油为稀释剂,对煤制气过程中产生的高浓度含酚废水进行了络合萃取处理,并用氢氧化钠溶液为反萃取剂对负载有机相进行了反萃取。分别研究了废水pH、TBP体积分数对萃取及氢氧化钠溶液浓度对反萃取的影响,并对萃取和反萃取过程中有机相的重复使用问题进行了探讨。结果表明,当废水的pH为3～6时,萃取率可达90%以上,CODCr去除率达到80%以上;当氢氧化钠质量分数为4%～10%时,反萃取率可达80%以上;TBP-煤油有机相可在萃取和反萃的过程中多次重复使用。

Gongye shui chuli, 2011 用四丁基氯化铵(TBAC)对Cr(Ⅵ)进行萃取,考察了稀释剂、水相pH、萃取剂浓度、水相体积、萃取振荡时间等因素对萃取效果的影响,得到最佳萃取条件,确定了萃取物中TBAC与Cr(Ⅵ)的物质的量比为1∶2。用5mol/L的氢氧化钠溶液对负载Cr(Ⅵ)的有机相进行反萃取,反萃取率达97%,浓缩结晶后以重铬酸钠的形式回收利用。

Gongye shui chuli, 2017 研究了2种离子液体[Omim]PF6（1-辛基-3-甲基咪唑六氟磷酸盐）和Aliquat 336（甲基三辛基季铵盐）对Cd（Ⅱ）的萃取性能，考察了离子液体种类、初始浓度、萃取时间、离子液体相与水相体积比（相比）及酸浓度对萃取率的影响。实验结果表明，[Omim]PF6对Cd（Ⅱ）的萃取率很低，而Aliquat 336对Cd（Ⅱ）的萃取率可以高达97%。随着废水中Cd（Ⅱ）初始浓度的增大，萃取率呈先略微升高，然后急剧下降的变化趋势。以Aliquat 336作为萃取剂，优化萃取时间为10 min，相比为1：5，
