摘　　要：研究冶炼渣中银的原子吸收测定方法。样品高温灼烧后以王水溶解,用火焰原子吸收分光光度计测定溶解液中的银。重点试验了灼烧温度、检测时间、溶样方法对检测结果的影响。在最佳检测条件下加标回收率为96.6%～102.2%,检测结果令人满意。方法操作简单、灵敏度高,适用于冶炼渣中银的快速测定。Determination method of silver in smelting slag by atomic absorption spectrometry was studied, in which silver in dis- solved solution was determined with flame atomic absorption spectrometry by dissolving a sample with aqua regia after burning it at high tem- perature. The research on the effects of burning temperature, testing time and method for dissolving sample on test results was highlighted. The standard recovery was 96.6% - 102.2% under optimal test conditions, and the test results were satisfactory. The method was suitable for rapid determination of silver in smelting slag due to its easy operation and high sensitivity.
