Influence of Various Factors on Arsenic Removal Using Ferruginous Manganese Ore

Abstract:

This paper dealt with the influence of various factors on As(Ⅲ) and As(Ⅴ) removal using ferruginous manganese ore, including environmental factors (temperature, time, light, pH) and coexisting ions(HCO₃^-,CO₃^2-,Cl^-,HPO₄^2-,SiO₃^2-,SO₄^2-,Mg²⁺,Ca²⁺,Fe³⁺). The comprehensive influence of various factors was also studied in orthogonal experiment. The results showed that the removal efficiency of As(Ⅲ) was up to 90.26%, while As(Ⅴ) was only 79.88%, under the conditions of that manganese ore dosage was 0.1000g per 50ml polluted water, reaction time was 1h, pH was 3.05, the concentration of arsenic was 204.45ug/l. Lower pH could achieve higher removal efficiency. Illumination was little beneficial to the removal efficiency. SiO₃^2-, HPO₄^2-, CO₃^2- and HCO₃^- could reduce the efficiency, due to competitive adsorption and electrostatic repulsion. The results of orthogonal experiment indicated that SiO₃^2- and HPO₄^2- were the greatest competitors with arsenic for adsorptive sites on the manganese ore, while temperature and time had no significant effect on arsenic removal.
