摘要：A process of producing a concentrated liquid biocide formulation is described.Mixed together are (a) bromine and (b) an aqueous solution of alkali metal salt ofsulfamic acid having a pH of at least about 12, in amounts such that (i) the active brominecontent of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio ofnitrogen to active bromine from (a) and (b) is greater than 1. A continuous process forproducing the concentrated liquid biocide composition is provided. This processcomprises continuously feeding into mixing apparatus (i) bromine and (ii) an aqueoussolution of alkali metal salt of sulfamic acid; the desired product is withdrawn from themixing apparatus at a rate sufficient to enable the continuous feeding to be maintained.Also described are methods for disinfecting surfaces and for sanitizing bodies of waterusing a single-feed, bromine-based biocide. These methods use concentrated liquidbiocide compositions comprising biocidally active bromine as the biocide.
