ABSTRACT:
A composition suitable for sanitizing water bodies consists of a mixture in compressed form of trichloroisocyanuric acid and an alkali metal bicarbonate. The mixture has a molar ratio of alkali metal bicarbonate to trichloroisocyanuric acid of from about 3:1 to about 1:1 and a moisture content of less than 0.2 percent by weight of the mixture.
The novel compositions, for example in tablet form, rapidly dissolve in water bodies such as swimming pools, spas and hot tubs to provide high concentrations of available chlorine for sanitizing the water. The compositions effervesce during dissolution and are resistant to thermal decomposition.
