摘　　要：采用原子荧光法对液体有机化工产品中的微量砷进行了测量。通过回收率试验、精密度试验及方法检出限试验验证了该方法对液体有机化工产品具有广泛的适用性。结果表明:原子荧光法对不同有机试样的回收率为87.5%~108.0%,相对偏差为5.27%~8.27%,方法检出限可达0.01 mg/kg。采用原子荧光法测定液体化工产品中的砷含量,试样需求量少,检出限低,整个过程所用试剂毒性小,应用范围较广,准确度和精密度均能满足测定要求。The trace arsenic in liquid organic chemical products is determined by atomic fluorescence spectrometry. The wide applicability of this method to liquid organic chemical products is verified by recovery test, precision test and method detection limit test. The results show that the recovery of different organic samples is 87.5%-108.0%, the relative deviation is 5.27%-8.27%, and the method detection limit is 0.01 mg/kg. In the determination of arsenic content in liquid chemical products by atomic fluorescence spectrometry, the demand of samples is small, the detection limit is low, the toxicity of reagents used in the whole process is small, the application scope is wide, and the accuracy and precision can meet the determination requirements.
