本文提出用泡沫塑料富集硫脲洗脱金的测定,与经典的活性碳吸附碘量法测定金及泡沫塑料吸附王水介质测定金的方法相比较,省去了灰化和转换介质等繁杂手续。泡沫塑料在王水介质中能定量的吸附金,经硫脲将金从泡沫塑料上洗脱下来后,可直接用原子吸收分光光度计测定。经试验证明,本法简便快速,选择性高,适用于测定矿样含金量在0.x～xx克/吨的范围。
In this paper, the determination of the gold which is enriched with thiourea by foam plastic is compared with the method of the classical activated carbon adsorption-iodimetric determination of gold and foam adsorption of aqua regia to determine gold. formalities. Foam plastic in the aqua regia can quantitatively adsorbed gold, thiourea gold from the foam on the elution can be directly determined by atomic absorption spectrophotometer. The test proved that this method is simple and rapid, high selectivity, suitable for the determination of gold content in ore samples in the range of 0. x ~ xx g / ton.
