using ,sulfuric acid,, with the Oxidation Reduction Potential (ORP) at +250mV or lower. The pH and ORP must be maintained at least for 45 minutes for the reaction to occur. It takes three parts of sodium bisulfite and one part ,sulfuric acid, to one part chromium. The reaction is shown in the following equation:

The acid in pure form is highly corrosive towards other materials, as it is an oxidant and a strong acidic nature. Additionally the pure acid is highly dehydrating, which means it will strip water away from any substance it comes into contact with. It is also hygroscopic, readily absorbing water vapor from the air. Upon addition of sulfuric acid to water, a lot of heat is released. Upon contact, pure sulfuric acid can …

15/11/2016, · In cases where the acidity in raw wastewater was relatively low, the addition of excessive acid was not feasible whereas the increase of FeS dose worked well. As indicated in Fig. 3 , the elevation of R FeS:As(III) from 3:1 to 5:1 contributed to the increase of As(III) removal efficiency from 42.3% to 99.6% (acidity = 1 mol/L as H 2 SO 4 ).
