Toxicity and Metal Corrosion of Glutaraldehyde-Didecyldimethylammonium Bromide as a Disinfectant Agent

Figure 1

Comparison of bactericidal efficacy of disinfectants on E. coli. Note: control without disinfectant treatment; U is a combination of 0.022% dimethyldimethylammonium chloride and 0.02% methenamine; GD is a combination of 0.005% GA and 0.001% DDAB. Treatment time is 0, 10, and 20 min. The means ± SD for at least three replicates are illustrated. P < 0.01.
