Abstract
Present paper deals with polarographic study of effect of maxima suppressors and supporting electrolytes on anodic waves of meta-hydroxy acetanilide and polarographic determination of meta-hydroxy acetanilide under optimum concentration of maxima suppressors and supporting electrolytes. The polarographic method has been developed to study qualitatively the effect of maxima suppressor (fuchsin) and supporting electrolyte (nitric acid) on oxidation wave of meta-hydroxy acetanilide. Polarograms of system were recorded from 500 to 1300 by using Rotating Platinum Micro Electrode as anode and Saturated Calomel Electrode as cathode on DC Recording Polarograph using Omniscribe recorder. It shows a similar behavior to that observed for paracetamol. It produces anodic wave at rotating platinum electrode. The oxidation yields the 3-N-acetylaminosemiquinone and represents a reversible reaction. Polarographically a value of 900 mV is found for decomposition potential of meta-hydroxy acetanilide. Wave analysis point to one electron-step for each wave. Waves of meta-hydroxy acetanilide are only proportional to concentration at low concentrations.
