摘　　要：样品经熔剂半熔后,水提取,用强酸性阳离子树脂除去大部分阳离子,在弱碱性介质中用ICP-M S测定溴、碘、砷、硒,样品分析结果与多目标推荐分析方法比对,相对偏差小于6.9%,另选取国家土壤一级标准物质12件对本方法的检出限、精密度、准确度进行测试,各项质量指标均能满足规范要求。Bromine, iodine, arsenic and selenium was determined by ICP-MS with sample pretreatment using semi-molten flux, water extraction and removing most cation using strong-acid cation exchange resin. Relative deviation is less than 6.9% of sample analysis by comparing muhi-objective recommended analysis method. The detection limit, precision, accuracy test of the method meet the requirements of the code by determined 12 national standard reference materials.
