✦ Synopsis

The polarographic behaviour of dithiodipropionic acid [S2(CH,-CH2COOH),] (referred to herein as RSSR) has been studied in aqueous and 20 % v/v methanol, ethanol, acetonitrile, DMSO and DMF media in the presence of 0.1 MKNO, and 0.01% thymol. The effects of changes in pH, concentration of RSSR, mercury pressure and different supporting electrolytes-KNO,, KCI, NaCI, NaCIO,, (.CH&N.Br and (C,H&N.Br--on the wave characteristics have been examined and the mechanism of the electrode reaction has b&n explained. Reversible and diffusion controlled cathodic waves were obtained both at lower and higher pH valu&.
