MetadataShow full item record
A simple method is presented for the potentiometric determination of small quantities of furosemide in a pure state and in pharmaceutical formulations, using 0.1 mol l-1 chloramine-T as titrant. In potentiometric titrations a platinum electrode was applied as the indicator one. The method is accurate and reproducible and can be applied to routine analysis of furosemide in quantities ranging from 1 to 15 mg.
