Estimation of the Biological Activity of Some Commercial Bleaching Solutions (Hypochlorites) on Pathogenic Bacteria
Keywords:Bleaching solutions, E.coli and Staphylococcus arueus, Antimicrobial, Microorganism, Hypochlorite’s.
Hypochlorites, the active ingredients in bleach, are an extremely useful chemical that have been used since
the 18th century as a disinfectant.Hypochlorite solutions are in general strong oxidizing agents. The study
included of five species of hypochlorite solutions widely used as commercial bleaching solutions (Shoof,
Oroplus, Alwazir , Lamoa and Fas) and their concentrations were confirmed chemically by potentiometric
titration methods previously and applicate their ability and efficiency against two types of bacteria (E.coli
and Staphylococcus arueus) which are isolated from human infected sample in general Heat hospital /Iraq.
The results revealed that all bleaching solutions have anti-bacterial influence against two species of bacteria
and more successful against Staphylococcus aureus than the E.coli especially with Alwazir solution give
high significant difference compared with other solutions ,also the outcomes showed sensitivity of bacteria
enhanced with concentrations of bleaching solutions. The study indicates the fast reduction rate in the 30S
reaction showed the immediate efficiency of Hypochlorites. Finally the current study suggest and encourage
to use hypochlorite solutions as antiseptics and disinfectants to killing species of bacteria which proved their
efficiency during this study
