RESUMEN
Objective To study killing effect of plasmas ozo ne water on microorganisms by plasmas ozone disinfection solution through plasma s ozone resulting from discharge along surface disinfection solution produced by machine and its effect factors. Methods Quantitative solut ion test was used to study killing action of plasmas ozone disinfection water to E. coli and staphyrococcus aureus, and to study its eff ect factors. Results Plasmas ozone water could kill 99.9% E. coli and staphyrococcus aureus after 15 min. The kill ing effect was affected by organism. With the increasing of organism concertrat ion, the killing efficacy increased. Conclusions Plasmas ozone can effectively kill microorgnisms in water and the efficacy was affected by org anism.
