摘要
以 2 .5 mol/L硫酸分解样品 ,过滤分离酸溶硼 ,在铁基体中用 ICP直接测定钢中微量酸溶硼 ,考察了测定的最佳条件及共存元素对测定的影响。所拟定的方法操作简便、快速、灵敏度高 ,检出限为 0 .0 35μg/m L ,样品测定下限为 0 .0 0 0 35 % ,样品加标回收率在 99.0 %～ 10 3.
To resolve test sample used of 2.5mol/L sulphuric acid,and to filter and separat acid soluble boron,acid soluble boron is directly determined in ferritic matrix used of ICP and the optimium condition of determination and influenct of coexistance elements to determination are reviewed.This method has the characters of convenient operation,quick speed,high sensitivity, and the detection limit is 0.035μg/mL and the determining low limit of sample is 0.00035%.The recovery yield of test sample is from 99.0% to 103 1%.
