摘要
本法采用了火焰原子吸收法测定废水中的铅和铬含量,经过查阅比较,发现样品前处理简便、快捷,克服了消化法繁琐、耗时以及直接进样法的易堵塞燃烧头、基线漂移等缺点,测定结果准确,方法线性良好,样品加标回收率为88.6%和91.4%。
This method was established for determination of Lead and chromium in wastewater by flame atomic absorption spectrometry.The method has produced not only satisfactory results,but also many advantages including easy pre-treatment of sample,convenience and base line drift.It was good linear relationship between Lead and chromium concentrations and instrument responses.It has a good sample recovery rate of 88.6%and91.4%.
