植酸中钙离子含量的离子选择电极测定法研究

Studies on the Determination of Calcium Ion Content for Phytic Acid with Ion Selective Electrode Methed

用离子选择电极法分别对标准溶液中钙离子含量、电极检测性能及ｐＨ值对离子选择电极的影响等进行了一系列测定和讨论，提出了离子选择电极测定植酸中钙离子含量的方法．同时我们把离子选择电极法和原子吸收法测定样品的结果加以比较，得出较为满意的结果．该方法简便、准确、迅速，所用仪器容易普及，适用于中小型植酸生产企业进行中间产品测试．

This paper makes a serial of determination and disscassion about the content of calcium ion in the standard samples,the examing property of the electrode and the acidity interfere to ion selective electrode.We put forward the method of determination of calcium ion content in phytic acid.This method is very convenient,fast,exact and this method is easy to pularization
