摘要
以DTPA提取土壤中的有效锰、铜、锌,不经分离富集,电感耦合等离子体质谱直接测定土壤样品中的有效锰、铜和锌,方法检出限分别可达0.042μg/L、0.039μg/L、0.028μg/L。通过对国家土壤有效态一级标准物质测试,测定结果基本一致;GBW 07412标准物质11次测定锰、铜和锌的相对标准偏差(RSD)分别为3.49%、3.72%、5.65%。
The amounts of Mn,Cu and Zn in soil were determined by ICP-MS. The metals in soil sample were extracted by DTPA,and determined by ICP-MS directly. The detection limit of method is 0. 042μg/L, 0. 039μg/L and 0. 028μg/L. The results are in agreement with national reference standards. The relative standard deviations are 3. 49%, 3.72% and 5.65% ,respectively.
