摘要
本文研究了氢氧化三烷基甲铵(转型的N_(163))—煤油体系从氰化液中萃取铜的机理。采用多种方法对萃合物的研究表明,铜以Cu(CN)_4^(8-)的形式被萃入有机相,萃合物的主要形式分别为Cu(CN)4·3(R_8CH_3N)和Cu(CN)_4·(ReCH_3N)_2(R_8CH_3N)。
In this paper the extraction mechanism of copper from cyanide solution by quaternary ammonium salt is studied. The compositions of extraction complex are determined by several methods and the results'from thelexperimen-tal data indicate that the copper is extracted into organic phase in the form of Cu(CN)48- and the composition of extraction complex may be Cu(CN)4. 3(R3 CH8N) and Cu(CN)4(R3CH3N)2(R3CH3N) respectively because of the partial poly-merizate existed in organic phase.
