摘要
本文研究了用二-n-己基硫醚萃取银的机理,并得到了一定的结果.在萃取过程中,形成的苹合物AgNO_3·(C_6H_(13))_2S,用所提出的机理解释了pH值、离子强度、萃取剂浓度及水相银(Ⅰ)初浓度的改变对分配比D值的影响.
The mechanism of extraction of silver (I) with di-n-hexylsufide (Di+S)was studied and the xylene was used as diluent.The extracted compound of AgNO3(C0H3)2S was found in the course of the extraction of silver (I) ion. It is successful to interpret the factors which effect on distribution coefficent D when the pH of aqueous-phase silver, the concentration of silver (I) ion and extractant of DHS are varied.
