Abstract
A spectrophotometric procedure for the simultaneous determination of mefenamic acid and paracetamol in a mixture is described. Using 0.01 M methanolic hydrochloric acid as solvent, the absorbance of the mixture is measured at 248, 279 and 351 nm. The concentration of each component can be calculated by solving two equations using two wavelengths, either 248 and 279 nm or 248 and 351 nm.
摘要
描述了一种用于同时测定混合物中甲芬那酸和对乙酰氨基酚的分光光度法。以0.01 M甲醇盐酸为溶剂，在248、279和351 nm处测量混合物的吸光度。通过使用两个波长（248和279 nm或248和351 nm）求解两个方程，可以计算出每种组分的浓度。
