摘要
采用密封溶样—质谱法(ICP-MS)测定岩石、矿物、水系沉积物、土壤中的银。该方法检出限为0.02×10-6;通过对7种国家一级标准物质中的银进行测定,检验该方法的准确度及精密度,测定结果与标准值相符,相对标准偏差小于5.00%。该方法简单、快速、灵敏度高,较好地满足了分析要求。
Silver in the rock,mineral,stream sediment and soil was determined by pressurizing decomposition-mass-spectrography.The detection limit is0.02×10-6by this method;By determining sliver in seven national primary standards tested the precision and accuracy of the method.Testing result conformed to standard values,and RSD was less than5.00%.The method was easy,rapid and high sensitivity,which meet the demand of analysis preferably.
