KINETIC STUDY OF THE OXIDATWE DECOLORIZATION OF XYLENOL ORANGE BY HYDROGEN PEROXIDE IN MICELLAR MEDIUM

The kinetics of the oxidation of xylenol orange tetrasodium salt by hydrogen peroxide was investigated in the presence of cationic surfactant (N-dodecylpyridinium chloride) & strongly basic media over the temperature range 20 - 35 °C. The kinetics studies were carried out as a function of di...
