摘要
采用王水溶样,活性炭动态吸附富集,电感耦合等离子体质谱法测定化探样品中痕量金,优化了样品分解、吸附条件、干扰消除等条件。结果表明,检出限0.13 ng/mL,RSD<4.7%,回收率97.63%～103.35%。该法准确可靠、简便快速,能满足化探样品检测要求。
A method for the determination of trace gold in geochemical prospecting samples by inductively coupled plasma mass spectrometry （ICP - MS ） with activated carbon collection was proposed. The decomposition of sample, conditions of adsorption and cancellation of interference were studied and optimized. The results showed that the detection limits of gold was 0. 13 ng/mL, recoveries were 97.63% - 103.35% and the relative standard deviation was better than 4.7%. The method can be applied to determination of gold in geochemical prospecting samples.
