摘要
用萃取第三相形成法，以Ｎ_（２３５）为萃取剂，煤油为稀释剂处理化学需氧量（ＣＯＤ）初始值高达５０ｇ／Ｌ以上的１－萘胺－８－磺酸生产废水。在萃取剂的浓度 为０．２０，相比１：１，萃取时间１０ｍｉｎ和室温条件下，二级错流萃取的ＣＯＤ去除率可达到９７％。
A Solvent extraction method for treating peri acid production wastewater is presented.The extraction is conducted by use of N_(235)as extractant and kerosene as diluent and the third phase is formed during the process.The wastewater with initial COD value over 50g/L is processed with following conditions:at ambient temperature and extractant concentration 20%,phase ratio 1:1,and extraction time 10min.After treatment the COD removal rate is up to 97% with two stages of cross current extraction.
