Abstract

In this research, a novel chemical solution was introduced as a cleaner reagent for removing metallic LEAD POLLUTION, as a fouling metal, from chromium surfaces. The CLEANER SOLUTION contains hydrogen peroxide (H2O2) as oxidizing and EDTA as a CHELATING AGENT of lead ions. The effect of some experimental parameters such as oxidizing and CHELATING AGENT concentration, temperature and stirring speed of the mixture (rpm) during the operation on the efficiency of lead cleaning procedure was investigated by means of sequential experimental method. The results of scanning electron microscopy (SEM/EDAX) showed that by using this procedure, the LEAD POLLUTION layer could be completely removed from the real chromium surfaces without corrosion of the original surface. However, our results show that under optimum conditions for the complete and fast removing of LEAD POLLUTION layer from chromium surfaces, that is, H2O2 6% (V/V), EDTA 30 mM, stirring speed of the mixture 50 rpm and temperature 30oC, to achieve the most cleaned sample, the total removal time of 3 g fouling lead layer is only 12 minutes. Finally, the results of this study illustrated that the efficiency of the proposed EDTA/H2O2 cleaning method is higher compared to the previous cleaning experimental techniques.
