【Abstract】 OBJECTIVE To establish an UV method to determine Phenytoin sodium in tablets.METHODS Phenytoin sodium was determined at 212 nm with 0.05 mol·L -1 NaOH as the solvents. RESULTS There was a good linear relationship between concentration and absorbance within the range of 3-15 mg·L -1 (r = 0.9998). The average recovery was 100.2% (n=5,RSD of 0.76%).CONCLUSION The method was simple, sensitive and accurate. It was suitable for measuring the contents of Phenytoin sodium in the tablets.更多还原
