[Comparative investigations on the efficiency of chlorine and ozone against bacteria and spores (author's transl)].

Abstract

This paper is concerned with the measurement of first order rate constants for the death of bacteria by chlorine and ozone. While the first order conditions for chlorine were achieved with the aid of a new instrument which works basing on the polarographic principle this was attained for ozone under steady state conditions. Besides differences of species some different properties for both oxidants were found as far as their bactericidal efficiency is concerned. They are discussed in this paper.
