  • Title: [On the sporocidal action of dibromoisocyanuric acid (author's transl)].
    Author: Wartusch B, Gottardi W.
    Journal: Zentralbl Bakteriol B; 1979 Jun; 168(5-6):533-7. PubMed ID: 506563.
    Abstract:
    Using the suspension test the action of dibromoisocyanuric acid (DBI) and--for the purpose of a comparison--elemental chlorine and Chloramine-T on three different spore strains at pH 7.0 and room temperature has been investigated. DBI proved to be a desinfecting agent by which at a concentration of 0.01 M positive halogene (= 1.45 g DBI/I) in 15--60 minutes (depending on the spore strain) a reliable kill can be achieved. Although using elemental chlorine shorter kill rates have been obtained (Chloramine-T was without any effect) DBI shows some advantages which also suggest its use in practice. As possible reasons for the differing efficiency of the three investigated substances the equilibrium concentrations of the hydrolysis products (HOCl resp. HOBr) and diffusion effects are discussed.
