本文采用王水分解样品,泡沫塑料吸附硫脲解脱后,于硫脲介质中无火焰原子吸收测定金.方法选择性好,灵敏度高,可测定矿石中0.001～0.2g/t个的金.
In this paper, the sample was decomposed by aqua regia, and the flame-retardant atomic absorption spectrometry was used to determine gold in the thiourea medium after the release of thiourea by foamed plastic.It has good selectivity and sensitivity and can measure 0.001-0.2g / t gold in ore.
