摘　　要：本文提出用铂灯244.0nm扣背景,火焰原子吸收光谱法直接测定浮选金精矿的硫脲浸出贵液、树脂交换贫液中金的新方法.该法可适用于高钠、高铁、高镁选冶作品溶液中金的测定.结果令人满意.This paper proposes a new method to determine the gold directly in the pregnant liquor of thiourea leaching of flotation gold concentrate as well as in the lean liquor following resin exchange by PAAS with background deducted by platinum lamp of 244.0nm. This method is fit to determine gold in sample solution of mineral processing and smelting containing great quantity of soduim or iron or magnesium. The test result is satisfactory.
