KINETIC SPECTROPHOTOMETRIC METHOD FOR THE QUANTITATIVE ANALYSIS OF STREPTOMYCIN SULFATE

Kinetic method has been developed for the quantitative analysis of streptomycin. The method is based on the oxidation of the drug with the mixture of potassium iodide and potassium iodate to form a yellow colored product. Two methods are adopted for the determination process, the initial rate method...
