矿石中金的快速测定——黄原酯棉富集分离-氢醌滴定法

RAPID DETERMINATION OF GOLD IN ORE—PRECONCENTRATION AND SEPARATION WITH XANTHATED COTTON FIBER-HYDROQUINONE TITRIMETRIC METHOD

研究了黄原酯棉振荡吸附 Au 的条件和解脱方法,并利用氢醌滴定法测定矿石中的金。方法的测定范围为0.5×10^(-6)～××·10^(-6)。方法的相对标准偏差RSD=1.35%,可用于矿石中金的野外快速测定。

The behaviour of preconeentration and separation of Au with xanthated cotton fiber and elution method is studied. The hydroquinone titrimetric method is used to determined Au in ore, the measurement range is 0.5×10^(-6)～××·10^(-6). The Au RSD is 1.35%. The method can rapidly determine gold in ore in field.
