测定氟化物中制备无氟清洗水的简易方法

A Simple Way to Produce Fluorine-free Water for Fluoride Testing

通过试验证明,一定浓度的KCl溶液滴加到去离子水中,对去除水中微量的F离子有良好效果。该方法简单易行,十分适合氟离子选择电极法测定中无氟水的制备。

The experiments show that if a certain concentration of KCl solution was added into deionized water,trace of F in the water can be removed.The method is simple.The water meets the requirement of testing with F-ion selective electrode method.
