Method for determining total chlorine amount and a kit for determining total chlorine amount

摘要

A method for determining total chlorine amount present in a sample by mixing the sample with a benzidine indicator solution comprising a benzidine compound capable of forming a dye by a reaction with a chlorine, wherein the hue of the formed dye changes depending upon the mole ratio of the chlorine to benzidine compound and determining the total chlorine amount from the hue. A kit for practicing the method incudes the indicator and a color scale for the hues of the dye.
