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 To establish a method for the determination of transportable arsenic in color clay by atomic fluorescence spectrometry. Methods After sample preparation, hydride generation atomic fluorescence was used to determine the migratable arsenic in color mud. Results Under the optimal experimental conditions, the correlation of the method was good (r = 0.9997), the relative standard deviation (RSD) was 0.51%, the detection limit (DL) was 0.028 9 ng / mL and the recovery was 96.6% ~ 102.5%. Conclusion The method is simple, accurate and sensitive, suitable for the determination of migratory arsenic in color mud.
