NaClO_3-HCl-NaCl分解试样I_2-CCl_4萃取光度法测定矿石中金

Spectrophotometric determination of gold in ore by extraction of I_2-CCl_4 afterdecomposition of sample with NaClO_3-HCl-NaCl

研究了用氯酸钠-盐酸-氯化钠分解试样,活性炭富集金,洗脱后,采用I2-CCl4萃取光度法测定矿石中金,取得了较为满意的结果。

A new method for the determination of gold in ore was introduced in the paperthe procedures of analysis,including the decomposition of sample with NaClO3,HCl and NaCl,the enrichment of gold by adsorption with activated carbon and after desorption the determination of gold by spectrophotometry with extraction of I2-CCl4 were adopted with satisfactory results
