摘要
本文研究了一水柠檬酸中微量铅、铁和钙的测定方法，并与标准加入法和湿法灰化法测得的结果进行了比较，获得了较为满意的结果。其回收率为９５．８％－１１０．３％，测量的相对标准偏差小于１０．２％。
In this paper a method for determination of Pb, Fe and Ca in citric acid monohydrate was studied, the experimental results were compared with the results from the standard adding and wet ashing methods.The results are satisfactory.The recoveries are between 95. 8% 110. 3 %, RSD is less than 10. 2%.
