| 摘 要： | 应用ICP-AES法测定高浓度Ca、Sr混合溶液,选择了合适的分析谱线。在较高浓度时,混合溶液中Ca、Sr之间无显著影响,配制样品及标准时可忽略两者之间的相互影响。测定时酸效应较明显。当待测样品与标准均采用水配制,待测样品总盐浓度在0.65%以内时,测定结果与标准浓度相对误差小于1%。

| Abstract: | The mixed solution that contained high concentration of calcium and strontium was determined by ICP-AES.The applicable analytical lines were chosen.The interaction between calcium and strontium is not serious in mixed solution at high concentration.The interaction can be neglected when preparing standard and samples.The acid effect is obvious.The relative error can be controlled within 1% when acidity of determined sample corresponds with standard sample and the salt concentration is less than 0.65%. |
