Experimental Studies on Elimination of Microbial Contamination by Hydroxyl Radicals Produced by Strong Ionization Discharge

Using fogdrops of OH. radicals to eliminate microbial contamination is an effective way to solve the current domestic and international problem. The results show that the threshold of OH. solution used in the experiment is 0.6 mg/L, the lethal time is 1 s, and the spray density of OH. solution is 21 μL/m2. The experimental results show that the OH. radical possesses the following advantages: celerity, low lethal concentration and spray density, short lethal time, and absence of secondary pollution.
