Experimental research of inactivation of Escherichia coli with hydroxyl radical liquor

The inactivation of Escherichia coli with hydroxyl radical liquor that strong ionization discharge produced was studied experimentally. The relation of initial content of bacterium, initial PH value, and temperature and ratio concentration of hydroxyl radical to the inactivation rate of Escherichia coli was studied. The results suggests that the inactivation rate of Escherichia coli is increased with increasing of the initial content of the bacterium, and the contact time and concentration of hydroxyl radical. The better initial PH value was 7.
