-
摘要: 本文用紫外分光光度法在257±1nm波长处测定对乙酰氨基酚泡腾片的含量,其浓度与吸收度的线性关系良好,相关系数r=0.99998.平均回收率为99.94%,变异系数为0.20%.本法简便、快速、结果准确。Abstract: A UV-Spectrophotometric method was successfully used at 257±1nm for determination of paracetamol in its effervescent tablet. The linear relationship between concentration and absorbance was well. The correlation coefficient was 0.99998, the average recovery 99.94%, and the coefficient of variation was 0.20%. The results show that method is simple, rapid and accurate.
