Abstract
A quick and accurate High Performance Liquid Chromatography (-PLC) method was established to detect the fluoride illegally added into tea.After extracted and absorbed by hot water,The sample was determined by HPLC and the background absorption was 1,2-Benzenedicarboxylic acid.The separation of fluoride was performed on a Agilent ZORBAX-ODS column (4.6mm ×.250mm,5μ m) using acetonitrile-.1mol/L 1,2-Benzenedicarboxylic acid (15:85,v:v) as the mobile phase with flow rate of 1.0 mL/min.The temperature was 35℃ and the detection was at 254 nm.The result showed that there is a good linear relation in the range of0.5 ～ 10.0μg/mL with correlation coefficient of 0.9998.The average recovery was 101.0％,RSD =1.67％.The method is accurate and feasible,suitable for determination of fluoride in the tea.关键词
