摘要
研究在氯仿溶液中用碳酸丙烯酯萃取银及某些影响因素,并提出银的萃合物形式及萃取平衡常数.在氯仿溶液中于22±1℃,pH0.2~3.0及15%PC-CHCl_3条件下,银的萃取率在97%以上.
The extraction of Ag(Ⅰ) with propylene carbonate in chloroform and the effects of the factors on the extraction are investigated. The extracted species of Ag(Ⅰ) and the apparent extraction equilibrium constant are presented. The extraction of silver(Ⅰ) in chloroform at 22±1℃, pH=0.2~3.0 and 15% PC-CHCl_3 is over 97%.
