Effect of Mnso4on the Chromium Removal from the Leather Industry Wastewater

Abstract: Chromium (VI) is one of the heavy metals in water and wastewater that has the most toxic characteristic. Consequently, it is dangerous for human and environmental health. Various methods are used for removal of the chromium from wastewater, and new methods have been developed in recent years. Recent studies and investigations on the removal of environmental pollution selected methods that were economical, of optimum efficiently and could be carried out easily. In this study, the removal of Cr6+ in the leather … Show more

“…The most widely used methods for removing heavy metals are chemical or electrochemical precipitation, both of which pose a significant problem in terms of disposal of the precipitated wastes [4,5], and ion-exchange treatments, which do not appear to be economical [6]. It has been reported that some aquatic plants [7,8], wood materials [9][10][11], agricultural by-products [12], clay [13], natural zeolite [14], turba (partially decomposed vegetable matter) [15,16], microorganisms [17][18][19], and other low-cost adsorbents [20] have the capacity to adsorb and accumulate heavy metals.…”

“…The highest adsorption efficiency of MnSO 4 was obtained at pH 9. Previous study by Ozdemir et al [2] using 530 mg/L MnSO 4 dose at pH value 9 in the wastewater sample showed about 96% removal of Cr (VI). In this case, because initial concentration TCr of the wastewater sample was relatively lower 15mg/L and was added 10 g/L of MNPs into it, the removal efficiency of TCr was relatively high than other studies [3], [11], [12].…”

“…Chromium exists in Cr (III) form in many biological proteins, nucleic acids and low molecules weighted ligands. Chromium (VI) form is much more toxic than chrome (III) form due to its oxidation potential and its penetration in the tissue [2]. Major Cr(VI) species include, HCrO 4 -, chromate (CrO cause severe damages to the human health including, but not limited to, liver and kidney damage, producing lung tumors, severe diarrhea, allergic dermatitis, skin irritation, internal hemorrhage and respiratory problems [3].…”
