5203 |a"Wide seasonal changes have been reported in the trihalomethane concentrations in water supplies. It is not known to what extent these changes can be ascribed to the effect of temperature on the haloform reaction or to what extent this is due to fluctuations is precursor concentration. This study reports the temperature dependence of the chloroform production from the reaction of chlorine with aquatic humic material (the major chloroform precursor in most natural waters) over the temperature range 2°C to 30°C at pH7 and pH11. The chloroform concentration was found to increase by a factor of 2.1 at pH7 and a factor of 1.7 at pH11 for each 10°C rise in temperature. The chlorination of several natural water samples under similar excess chlorine conditions yielded virtually the same temperature coefficients for total trihalomethane production"--Abstract.
