Abstract
The present study is an evaluation of the bactericidal efficiency of calcium hypochlorite, trichlorocyanuric acid and potassium dichlorocyanurate with and without the addition of 50 mg/1 of cyanuric acid against Escherichia coli, Streptococcus faecalis and Staphylococcus aureus in water of pH 7.2, alkalinity of 50 mg/1 and temperature of 25[degree]C. Although all 3 compounds were effective against these organisms in the absence of added cyanuric acid their action was retarded by the addition of 50 mg/1 of the substance; a 4 to 8-fold increase in the amount of "free" chlorine residual was necessary in the presence of cyanuric acid to attain the same degree of inactivation of the same organisms in the same interval of time.This publication has 1 reference indexed in Scilit:
