THREE WAVELENGTH SPECTROPHOTOMETRY OF SMPZ AND TMP IN SULFA COMPOUND TABLETS
Sulfamethoxypyrazine (SMPZ) and trimethroprim (TMP) in sulfamethoxypyrazine compound tablets were determined with three wavelength spectrophotometry without any preliminatry separation. The compound tablets were ground and dild. with 0.1 N HCl at 70℃, and analyzed with 751 G spectrophotometer at 229 nm, 304 nm. Recoveries were 99.65±0.31％ and 98.73±0.31% respectively.
