摘要
采用碳酸钠—氧化锌半熔法分解试样，火焰原子吸收光度法测定铜阳极泥中０Ｘｋｇ／ｔ－ＸＸｋｇ／ｔ银，测定结果可满足工业生产原料分析及生产质量控制分析要求。
Because of the serious dust pollution,complex analytical and long treatment process,the traditional melting method of extracting silver,as halide form in slime failed to meet the requirements of industrial production.Taking Eshka method,a fritting method of the sodium carbonate zinc oxide to resolve samples,the author uses the flame atomic absorption spectrophotometer to measure silver in the copper slime,obtaining precise and high speed results.With small pollution,low cost and simple operation,the method can be well used in the analysis of industrial raw materials and control of productive process and product quality.
