| Abstract: | A new method of derivative three-wavelength spectropothometry has been developed for the simultaneous determination of sulfamethoxazolum (SMZ) and trimethoprimum (TMP) contained in ta-bellae sulfamethoxazolum composite. The method takes the advance of the hyperchromic effect and blue shift effect of E_2-band and the B-band of TMP, which reduced the overlap between the TMP E_2-band and the B-band of SMZ in 1, 4-dioxane. It also utilizes the command chain function of UV-265 spectrophotometcr. In this way, its sensitivity, accuracy, and speed of determination are improved. The method has been used for the analysis of commercial drug and the result is the same as that found in the pharmacopoeia. |
