摘要
研究了用ＴＢＰ－Ｐ２０４－ＳＰＡＮ８０－煤油高效乳状液膜体系分离富集铬（Ⅵ），实验测量了外相ＰＨ值、协同流动载体（ＴＢＰ＋Ｐ２０４）浓度、表面活性剂、ＳＰＡＮ８０和内相ＮａＯＨ浓度对Ｃｒ（Ⅵ）迁移、富集的影响，结果表明：只有Ｃｒ（Ⅵ）能从常见离子中得到满意的分离和富集。该法已成功地应用于富集和测定钢材酸洗液和工业废水中微量铬。
Experiments have been conducted on segregation and enrichment of trace Cr () by using high efficient emusion film of kerosene series TBP-P204-SPAN 80. Effects of PH value of the external phase, concentration of thecoordinated flowing carrier (TBP+P204) and concentrations of the surface-active agent, SPAN 80 and the internal phase NaOH on the movement and enrichment of Cr () have also been verified in the experiments. Results show that only Cr () can be effectively segregated and enriched out of the common i...
