水中黄磷测定的方法研究

摘要

This paper researches the determination of yellow phosphorus in water with cyclohexane extraction-molybdenum antimony anti-spectrophotometric method. The standard curve is drawn and the detection limit is measured. The lowest detection limit of the method is calculated. The lowest testing quality in laboratory is 0.995μg, and the minimum detection concentration is 1.17μg/L, both were lower than the standard method with lowest testing quality 2.5μg and minimum detection concentration 2.5μg/L, meeting the monitoring and anal-ysis requirements.%本文对环己烷萃取-钼锑抗分光光度法测定水中黄磷方法进行了研究，通过对标准曲线的绘制和检出限的测定，计算出环己烷萃取-钼锑抗分光光度法测定黄磷的方法最低检出限，实验室最低检测质量为0.995μg、最低检测质量浓度为1.17μg/L，均低于标准方法最低检测质量2.5μg、最低检测质量浓度2.5μg/L，满足监测分析要求。
