摘要
采用气相分子光谱法,使用上海北裕全自动COD_(Mn)分析仪,通过对国家标准样品、黄河澄清水、黄河含沙水体样品进行分析测试,探讨气相分子色谱法测试黄河水体中高锰酸盐指数的方法检出限、精密度、准确度的指标。
In this paper, gas-phase molecular spectroscopy and Shanghai Beiyu full-automatic CODMn analyzer were used to analyze and test the national standard samples, the clarified water of the Yellow River and the sediment-lad. en water of the Yellow River. The detection limit, precision and accuracy of the method of gas-phase molecular chro. matography for the determination of permanganate index in the water of the Yellow River were discussed.
