摘　　要：目的建立原子荧光光谱法测定彩泥中可迁移砷的方法。方法样品前处理后,用氢化物发生原子荧光法测定彩泥中的可迁移砷。结果在优化的实验条件下,该方法的相关性好（r=0.9997）,相对标准偏差（RSD）为0.51%,检出限（DL）为0.028 9 ng/mL,加标回收率为96.6%~102.5%。结论该方法操作简便、准确灵敏,适用于彩泥中可迁移砷的测定。Objective Establish the method can be used to assay the content of locomotive arsenic in color plasticine.Methods After primary treatment of color plasticine,hydride generator-atomic fluorescence spectrometry was used to measure the content of locomotive arsenic in color plasticine.Results Under the optimized experimental conditions,perfect correlation was observed（r=0.999 7）,relative standard deviation（RSD）,detection limit（DL）,and standard recovery rate were 0.51%,0.028 9 ng/ml,and 96.6%~102.5%,respectively.Conclusions This method is simple,accurate,sensitive,and can be used to assay the content of locomotive arsenic in color plasticine.
