原子荧光光谱法测定环境空气中锑

采用过氯乙烯滤膜采集环境空气中锑，盐酸-氢氟酸混酸体系微波消解滤膜，原子荧光光谱法测定锑。方法前处理操作过程简单、省时、酸用量少、环境污染小，方法的灵敏度和准确度都有很大的提高。采样体积为300L时，空气中锑的最低检出质量浓度为0.002mg／m3。

Antimony Determination by Atomic Fluorescence Spectrometry

Antimony in air was sampled using perchloroethylene filter.The filter was dipped into hydrochloric acid and hydrofluoric acid system and digested by microwave.Atomic fluorescence spectrometry was used to detect anti-mony after.This process is simple and time-saving with easy pretreatment,less amount of acid,and less negative impacts on environment.In addition,the accuracy and precision of the process is better than previous methods. The detection limit of antimony in air is 0.002mg/m3 when the volume of air sample is 300 liters when this process was applied.
