Abstract
In order to reutilize waste liquor spent for deodorization, decomposition of sodium hypochlorite remaining in it was tried using columns packed with activated carbon (coal-base).
The optimum condition was found to be as follows; temperature: a room temperature, pH of the liquor: around 10, flow rate of the liquor: 6m/h. Under this condition, 400-800 ppm (w/w) of sodium hypochlorite was decomposed almost completely at the decomposing rate of ca. 0.5g NaOCl/g carbon.
