摘　　要：主要研究了原子荧光光谱法测定煤中砷含量的方法,该法回收率为(95.75~98.34)%,RSD<2.36%。通过与砷钼蓝分光光度法测定煤中砷含量比较,和对该法的精密度和准确度进行探讨,结果表明,该法操作简单,快速,灵敏度高,测定砷浓度范围大,适用于煤中砷含量测定。This paper mainly studied the atomic fluorescence spectrometry determination of arsenic in coal, the method of recovery of the method （95.75 - 98.34）%, RSD 〈 2.36% . With arsenic molybdenum blue spectrophotometric method determination of arsenic in coal, and discusses the accuracy and precision of this method, the results show that the method is simple, rapid, high sensitivity, the determination of arsenic concentration in large range, is suitable for the determination of arsenic in coal.
