| Abstract: | 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. |
