ICP-MS测定矿产样品中的金

Determination of gold in mineral samples by Inductively Coupled Mass Spectrometry

试样经灼烧后用王水溶解,活性炭吸附,灰化灼烧除炭,再用王水溶解金,以ICP-MS进行测定。本方法具有简便、快捷、检出限低,线性范围宽等优点,经加标回收试验,结果稳定、可靠。

The sample was dissolved in aqua regia after ignition, absorbed by activated carbon, carbon removed by incinerated ignition and dissolved and determined gold by aquaregia with the method of inductively coupled mass spectrometry. This method was characteristics of easy, quick, low detection limit and linear range. Through standard recovery, the results were stable and reliable.
