摘要： Methods and compositions for generating stable, residual disinfectants during the ozonization of water, comprising the carrying out the ozonization of water in the presence of bromide ions and an effective amount of a hypobromite ion scavenger possessing imide and/or amide functionality that preferentially converts hypobromite ions to biocidal, ozone-stable derivatives thereof to thereby suppress the catalytic decomposition reaction of ozone with hypobromite ions. The methods and compositions of the present invention are useful for water disinfection and algae control, generally.
