Abstract

This study used combination of ortho-phthalaldehyde(OPA) and quaternary ammonium surfactants (QAS) with different concentration to kill Escherichia coli, Staphylococcus aureus, Candida albicans and Aspergillus niger conidia. The concentration of the combination disinfectant to kill Escherichia coli, Staphylococcus aureus and Candida albicans was 75mg/L OPA and 30mg/L QAS within 10 min, respectively. The average killing log value was above 4 when Aspergillus niger conidia was exposed in 3.75g/L OPA and 1.50g/L QAS for one hour. Then the effects of time, temperature and organic concentration on the bactericidal effect were measured. And the metal corrosion and stability of the combination disinfectant were determined. In addition, these results showed that the combination disinfectant had a high efficiency of bacteria killing and the concentration of organic affected its bactericidal effect. The average killing log value gradually increased along with the temperature within 10°C. to 40°C. And the combination disinfectant also has the advantages of low corrosive of metal, good stability and so on.
