Description
Reduction of carcinogenic trihalomethanes (THM) formed in drinking water by chlorine disinfection is a serious problem in the world at present. In advance of a study to depress the formation of THM by a simultaneous use of radiation and ozone, the experimental methods of measuring of THM and total organic halogen (TOX), chlorine treatment and preparation of humic samples were reviewed. This study proved that (1) chlorination in a vial enables the simultaneous measurement of THM and TOX, (2) addition of nitric acid depresses the hydrolysis of halogenated organics, (3) water-soluble sodium bisulfite can be used as a good dehalogenating reagent, and (4) humic samples prepared from humus are suited for the experiment of chlorine treatment of raw drinking water.
