Abstract
A simple and rapid permanganate value test procedure for the estimation of COD, based on the photometric measurement of the remained permanganate after the color bleaching by oxygen demand organics during digestion, has been described. Optimized conditions were 1% NaOH, 0.6mM <TEX>$KMnO_4$</TEX>, with a closed reflux in the boiling water bath for 90 sec using sample size of 5mL.
