离子选择电极法测定牙膏中的含氟量

Determining the Content of Flourine in the Toothpaste by Means of Selecting Electrode Through Flourine Ion

采用氟离子选择电极法测定氟含量,具有简便、快速、灵敏、选择性好等优点,最低检出浓度为0.05mg/L,适用浓度范围宽,在测定牙膏含氟量中取得良好效果。

This article deals with the selection of electrode through flourine ion. This method has merits of easy operation, consuming short time and high sensitivity, which can be used to determine turbidity and coloured samples. The lowest testable density is 0.05mg/L. It can be used for wide scope of density and has already been effectively in the determination of the content of flourine in the dentifrice.
