Abstract

The aim of our study was to develop an optimized method for the determination of fluoride content in rice. During determination, ultrasonic extraction was used and the calculation method of fluoride content was modified. The results showed that the relative standard deviations(RSD) of this method ranged from 2.9% to 8.4%, the averaged recovery rate ranged from 90.8% to 102.5%, respectively. The relative deviations between the Ion Chromatography and this method was less than 10%, all of the parameters meet the demands of determination. The method had the virtues of low costs, easy to operate, good repeatability, high recovery rate, and can meet the needs of rice detection.
