摘要： 本文研究了1,2-双(正-丙基硫代)乙烷(BPrTE)、1,2-双(正-戊基硫代)乙烷(BATE)、1,2-双(正-辛基硫代)乙烷(BOTE)和1,2-双(苯基硫代)乙烷(BPTE)对银的萃取.讨论了硝酸浓度、稀释剂RS(CH2)2SR(L)中R基因对萃取银的影响.L可从大量贱金属和氯化物中定量地萃取银,银和配体可形成组成为Ag:L=2.5:1,2:1,3:2,1:1,2:3,1:2系列配合物.

Abstract: In this paper the extraction of silver with RSCH2CH2SR(L)[R=n-C3H7(BPrTE),n-C5H11(BATE), n-C8H17(BOTE), C6H5(BPTE)] is studied. The effects of concentration of nitric acid, diluent and Rgroup on the extraction are discussed. It is found that silver can be quantitatively extracted from large amount of common metals and chloride in nitric acid medium. The study on the solution complexes and the analyses of solid and liquid complexes indicate that the composition of complexes is in ratio Ag : L=2. 5=1, 2 : 1, 3 : 2, 1 : 1, 2 : 3 and 1 : 2.
