| Abstract: | A fast fading spectrophotometric method was established for the determination of meclofenoxate hydrochloride based on the reaction of meclofenoxate hydrochloride with eosin Y in the Clark-Lubs buffer media (pH 3.6). The apparent molar absorptivity of complex was 1.059× 10~4 L·mo~(-1)·cm~(-1) at 506 nm. Beer's law was obeyed in the range of 2 - 18 μg/ml for meclofenoxate hydrochloride. |
