螯合树脂富集I_2-CCl_4萃取光度法测定矿石中的金

Determination of gold in ore by extraction photometric method of I 2 CCl 4 after enrichment by using chelating resin

利用ＮＫ８３１０螯合树脂富集金，用硫脲盐酸解脱液解脱后，采用Ｉ２ＣＣｌ４萃取光度法测定矿石中的金，取得了较为满意的结果。

In this paper,the gold are enriched by using NK8310 chelating resin.After removing by liberating liquid of thiourea hydrochloric acid,the gold in ore are determined by extraction photometric method of I 2 CCl 4,achieving satisfactory result.
