摘　　要：本文研究了ＴＢＰ萃淋树脂分离、硫代米酮－十六烷基三甲基溴化铵分光光度测定矿石中金的方法。检出限为０．０１μｇ／ｍＬ，相对标准偏差约为５％。方法用于矿石及尾矿中金的测定，取得满意的结果。spectrophotometric method for determination of trace gold in the ores with thiomichler's ketone(TMK)-cetyltrimethyl ammonium bromide(CTMAB) is described. The interfering ions can be separated with TBP levextrel resin. The detection limit is 0.01 μg/mL, and the relative standard deviation is about 5%. The method has been applied to the determination of trace gold in the ores with satisfactory results.
