15 صفحه اولDetermination of Triiodide Ion Concentration Using UV-Visible Spectrophotometry†
The concentration of iodine species can be measured using several different analysis methods. One of the most wellknown methods involves iodine titration with a thiosulfate solution. Total iodine can be analyzed using spectrometry, such as inductively coupled plasma-atomic emission spectrometry (ICP-AES), atomic absorption spectrometry (AAS) and inductively coupled plasma-mass spectrometry (ICP...
متن کاملDetermination 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...
