摘要
对3种传统测钙方法(酸碱滴定法、络合滴定法、氧化还原滴定法)的准确度进行了比较研究,结果表明:采用络合滴定法测定Ca,准确度高,耗时短,且方法简便易行,更适合用于教学实验和常量钙的快速测定.
The accuracy of the traditional three kinds of methods of the analysis calcium （acid-base titration,complexometric titration,redox titration method） was investigated.The result showed that the method of complexometric titration for determination of calcium had the characters of high accuracy,short time-consuming and easy operation,and this method is more suitable for teaching experiments or quick and systemic analysis of macro calcium.
