【摘要】 提出一种乙烯气中砷的富集、消解方法，详细地考察了实验条件。用GFAAS法对乙烯气中砷含量进行了测定，相对标准偏差＜4．7％，测定结果与氧化物原子荧光法测定结果相吻合。更多还原

【Abstract】 A new method was established for concentration and dissociation of arsenic in ethene, the experimental conditions were investigated in detall. The content of arsenic in ethene was determined byGFAAS. The retative standard deviation is less than 4. 7%, the results obtained by this method areconsistent with those obtamed by hydride generation XRF.更多还原
