Abstract

Pulse Polarographic Determination Of Dapsone In Tablets

Author(s): D. K Sharma, N Verma, K Prasher, Jasvir Singh

The sulphone group present in dapsone is smoothly and quantitatively reduced at dropping mercury electrode in dimethylformamide medium in the presence of pyridinium perchlorate, yielding a diffusion controlled wave at -1.50 V vs SCE, has been made the basis of present method. The determination has been made by normal pulse and differential pulse polarography by linear calibration plots.
