摘要：In order to estimate the rate of disappearance of free available chlorine during storage in water tanks, the rate of vaporization of free available chlorine was studied and the rate of the chlorine consumption caused presumably by components in water supply, though the components were unknown, was also investigated. The rate of vaporization was proportional to the air-water interfacial area, but it was independent of the water level and the initial concentration of free available chlorine. A linear relationship exists between the logarithm of the rate of vaporization and the reciprocal of absolute water temperature. The consumption caused by the components in water supply was approximately accounted for the first order reaction. However, the rate constant for consumption varied inversely as the initial concentration of free available chlorine. The constant was not a true one. The apparent rate constant was proportional to the fourth power of water temperatnre. Our proposed model was able to give an adequate explanation of the whole course of the disappearance of free available chlorine during storage in water tanks.
