Determination of Sulfamethoxazole and Trimethoprim in Pharmaceuticals by Visible and UV Spectrophotometry
A method for the simultaneous determination of sulfamethoxazole (SMX) and trimethoprim (TMP), based on a direct determination of SMX after diazotization and coupling with 2-naphthol by visible spectrophotometry and an indirect determination of TMP in the UV region by difference was developed. By the suggested procedure, it was possible to analyze SMX and TMP in pharmaceutical preparations witho...

متن کاملSimultaneous Determination of Barbiturates and Salicylates by Ultraviolet Spectrophotometry.
A rapid method based on UV spectrophotometry is described for simultaneous determination of salicylates and barbiturates in serum. While barbiturates have no absorbance above 280 m and extracted normal serum has insignificant absorbance, salicylate has a maximal absorbance peak at 296 mjh, which is proportional to concentration. The barbiturate concentration can be calculated from absorbance di...
