| 摘 要： | 样品经草酸?草酸铵溶液(Tamm溶液)浸提,分取浸提液,蒸干灼烧破坏草酸盐,制备成硫酸介质溶液,采用端视电感耦合等离子体发射光谱法测定土壤中有效钼。方法检出限(3s)为0.013μg/g,精密度(RSD,n=12)为2.13%~6.70%。经国家一级标准物质验证,测定值与标准值吻合。

| Abstract: | A method for the determination of available molybdenum in soils by end-view inductively coupled plasma-atomic emission spectrometry(ICP-AES) was described.The available Mo in soil samples was extracted by oxalic acid-ammonium oxalate.A portion of the extracted solution in a beaker was then put on a hot plate and heated to dry in order to decompose oxalate,the residues were then dissolved with sulphuric acid solution.The available molybdenum in solution is measured by end-view ICP-AES.The detection limit of method is 0.013 μg/g for available Mo.The method has been applied to the determination of available Mo in National Standard Reference Materials and the results are in good agreement with certified values with precision of 2.13%～6.70%RSD(n=12). |
