摘要
本文采用泡沫塑料吸附，氢醌还原滴定测定矿石中金的含量，并用于生产测试。
A new method for the determination of An by using polyurethane foam adsorption and hydroquinone reductive titration is expressed. The detection licest is 0. 2 × 10-6. The linear range of determinationis 0. 5 × 10-6 ￣ - 35 × 10-6. The metal ho ho applied to the pracical determination of An in ore samples.
