建立了泡沫塑料吸附-电感耦合等离子体原子发射光谱法测定地质样品中的金的方法,采用王水溶解地质样品中痕量的金,经泡沫塑料吸附富集,结合电感耦合等离子体原子发射光谱法进行测定。实验表明,方法的加标回收率为94.4%~111.0%,对国家一级标准物质进行测定,结果与认定值一致,方法的相对标准偏差RSD为3.2%~12.8%。 A method for the determination of gold in geological samples by foam adsorption-inductively coupled plasma atomic emission spectrometry was established. The trace amounts of gold in geological samples were dissolved by aqua regia and absorbed by the foam plastic. Inductively coupled plasma atomic emission spectrometry Method for determination. The experimental results showed that the recoveries of the method were 94.4% ~ 111.0%. The results of the determination were consistent with the certified values. The relative standard deviation (RSD) of the method was 3.2% ~ 12.8%.
