摘要
用HNO3和HCl的混合酸分解腐殖酸样品 ,选用波长 2 0 8.96nm于ICP测定。分析结果与比色法、容量法吻合。相对标准偏差为 1 .0 5 % ,回收率为 97.87%～ 1 0 4.45 %。
The humic acid samples are decomposed by the mixed acid of HNO 3 and HCl and then the decomposed samples are determined.The resultsare as same as those of colorimetric method and volumetric method.The relative standard error is 1.05% and the recovery rate is between 97.87% and 104.45%.
