was studied through comparing the damage behavior of 304 stainless steel in dilute sulfuric acid to that in distilled water by a reciprocating tribotester. The re-passivation behavior, the surface... of stainless steel in dilute sulfuric acid was caused by the steel’s mechanical removal and electrochemical dissolution. The wear mechanism of stainless steel is abrasive wear, which mainly consists of micro......
as the reductant in a dilute sulfuric acid medium. The effects of banana peel amount, H2SO4 concentration, reaction temperature, and time on Mn leaching from the complex LGMO were studied. A leaching efficiency of ~98% was achieved at a leaching time of 2 h, banana peel amount of 4 g, leaching temperature of 120°C,manganese ore amount of 5 g, and sulfuric acid concentration of 15 vol%. The phase......
, 8]. Sulfuric acid is usually employed to adjust the pH value of COPR during the hydro-remediation process. Although the sulfuric acid favors the leaching of Cr(VI) in CAC and hydrotalcite [9-10...) [11-16]. Therefore, it is necessary to search for the substitute of sulfuric acid to treat COPR effectively. Up to now, less literatures have been involved in treating COPR with hydrofluoric (HF) acid......
