摘　　要：分散液液微萃取技术是2006年提出的一种新型萃取技术,主要应用于分析领域。本文介绍了运用一种新型含硫酮结构类离子液体为螯合剂,将分散液液微萃取技术运用于金属离子富集过程,并对萃取条件进行探究,分析了疏水性离子液体的选择和用量、分散剂的选择和用量、超声处理时间等因素对萃取结果的影响。结果表明:将螯合剂溶于正庚醇试剂形成混合液,按照混合液:水相体积比为1:16的比例混合,加入甲醇作为分散剂,且其与水相的体积比为1:16,充分混合,超声处理1min,该条件下钯离子的萃取率最高。Dispersed liquid microextraction(dlme)is a new extraction technology proposed in 2006,which is mainly used in the field of analysis.This paper introduces the application of microextraction technology of dispersing liquid to metal ion concentration process by using a new type of sulfo ketone structure ionic liquid as chelating agent,and probes into the extraction conditions,analyzes the influence of the selectionand dosage of hvdrophobic ionic liquid,the selection and dosage of dispersant,ultrasonic treatment time and other factors on the extraction results.The results showed that:the chelating agent was dissolved in n-heptanol reagent to form a mixed solution,which was mixed according to the ratio of the volume ratio of the mixed solution:water phase 1:16,and methanol was added as the dispersant,and the volume ratio of the chelating agent and water phase 1:16,which was fully mixed.and ultrasonic treatment for 1 min.under this condition.the extraction rate of palladium ion was the highest.
