... phenomenon to only stainless steel. Microorganisms in marine biofilm caused OCP ennoblement. Cathodic polarization curves elucidated that synergistic effects of hydrogen peroxide and acidity by marine biofilm probably caused OCP ennoblement in natural seawater. Furthermore, we analyzed microbial consortia...

... for equipment cleaning are changing. Chemical oxidation (e.g. the use of potassium permanganate, hydrogen peroxide, sodium hypochlorite or "bleach") is one technique that is being used for the removal of these compounds. This paper will compare the effects of chemical oxidation, especially potassium...

...Pulp bleaching equipment is typically built from titanium to withstand the corrosive effects of chlorine based bleaches. In order for hydrogen peroxide to displace chlorine dioxide, titanium corrosion resistance must extend to hydrogen peroxide bleaching solutions which can be alkaline or acidic...
