摘要
研究了以苯为萃取剂,用气相色谱——火焰光度法测定废水中的微量黄磷。结果色谱分离良好,萃取率大于94％,水样易于保存,溶剂和杂质不干扰测定,水样加标回收率大于88.48％,精密度重复测定的变异系数不大于3.2％,定性检出限为2μg/L,定量检出限为6μg/L。
By taking benzene as extractant and using gas chromatography-flame photometry to determine trace yellow phosphorus in waste water, the result was good. Rate of extraction was greater than 94%, water sample easy to preserve, did not interfere with solvent and impurities, the recovery rate was greater than 88.48%, variation coefficient was 2.3%, the qualitative detection limit was 2μg/L, and quantitative detection limit was 6μg/L.
