摘要
介绍了电感耦合等离子体质谱仪(ICP-MS)测定碳酸钙中痕量铅的方法。碳酸钙样品经硝酸溶解,引入ICP-MS直接测定,选取^(208)Pb为测定同位素,积分时间为0.9 s。方法的加标回收率为106.5%,相对标准偏差0.88%～3.01%。
The method of determination of trace lead was introduced. Calcium carbonate was dissolved by nitric acid, and determinated directly by ICP-MS, ^208 Pb was the selected isotope, the integral time was 0.9 second. The recovery was 106.5%, and the relative standard deviation was 0.88%～3.01%.
