An effective chloride selective electrode method was developed for determinating the chlorides content in glycine. The method had simple operation and high accuracy, without sample preparation. The calibration cureve showed a good linear correlation within the concentration range of 20~200 μg/mL ( r=0. 9998 ) . The relative standard deviation was 2. 16%, and the recoveries were 96% ~109%. In conclusion, this method was good enough to determinate the chlorides content in the product of glycine, which could afford a rappid guidance for controlling the chloride content in the extraction section of producing glycine.
