Quantitative Determination of Penicillins by Iodometry Using Potassium Hydrogen Peroxymonosulfate
The kinetics and stoichiometry of S-oxidation of semisynthetic penicillins (amoxicillin trihydrate, ampicillin trihydrate, sodium salt of oxacillin and ticarcillin disodium salt) by potassium hydrogen peroxymonosulfate in aqueous solutions at pH 3-6 was studied by iodometric titration: 1 mol of KNSO...

| Summary: | The kinetics and stoichiometry of S-oxidation of semisynthetic penicillins (amoxicillin trihydrate, ampicillin trihydrate, sodium salt of oxacillin and ticarcillin disodium salt) by potassium hydrogen peroxymonosulfate in aqueous solutions at pH 3-6 was studied by iodometric titration: 1 mol of KNSO5 per 1 mol of penicillin, the quantitative interaction is achieved in 1 min (time of observation). A unified method was developed and the possibility of quantification of penicillins by the iodometric method using potassium hydrogen peroxymonosulfate as an analytical reagent was shown. |
