| 摘 要： | 在硫酸铵存在下,乙醇水溶液能够分为醇/水两相,在分相过程中,Pd2+与KBr和C2H5OH2+生成的PdBr42-]C2HsOH-2+]2三元缔合物能被乙醇相萃取,使Pd2+与Ru2+、Ag+、Cu2+和Pb2+完全分离。该法在微量钯的分离和富集分析中有一定的实用价值。

| Abstract: | The ethanol aqueous solution could be well divided into ethanol/water two phases in the presence of ammonium sulphate,and the ternary compoundPdBr42-]C2H5OH2+]2 was formed by C2H5OH2+,Pd2+ and potassium bromide,that could be completely extracted during the dividing phase process,and Pd2+ could be entirely separated from Ru3+,Ag+,Cu2+ and Pb2+ by extraction.This method has the contain value for separation and enrichment of trace palladium. |
