测定环境空气中砷及其化合物的方法改进

Improvement on the Determining Method of Particulate Arsenic and Arsenic Compounds and Arsenic Trioxide Vapour in Atmosphere

对《空气和废气监测分析方法》中砷的采样和测定方法进行了改进,并在云南某炼铜厂环境空气中含砷监测进行了实际验证。结果表明,方法的检出限、精密度、准确度均能满足测定的要求,并且更适合测定高浓度砷。

The ＂ air emission monitoring and analysis methods＂ in the sampling and testing methods for arsenic has been improved. The method has been verified in a copper smelter in Yunnan. The detection limits, precision, accuracy can content the detect demand and this method is more suitable for determination of high concentrations of arsenic.
