ABSTRACT:
A method for providing aqueous solutions of HOBr or HOCl which includes adding bleach (NaOCl) to a solution of HBr or HCl an identified absorbance or color change in the resulting solution is detected. Dialkylhydantoins are optionally added to the resulting solution to suppress the formation of halate ions. The method provides a simple and reliable method for producing accurately defined solutions of hypohalous acids, which are useful in a variety of ways, including for disinfecting, cleaning, and odor control purposes.
