ADSORPTIVE REMOVAL OF Pb(II), Zn(II), Cu(II) IN THE WASTEWATER FROM A FLOTATION MINERAL FACTORIE IN CHO DON DISTRICT, BAC KAN PROVINCE BY USING MODIFIED LATERITE

Abstract

   This paper focus on adsorptive removal of Pb(II), Zn(II), Cu(II) in the wastewaterfrom a flotation mineral factorie in Cho Don district, Bac Kan province by modifiedlaterite. The results showed that the real of adsorption capacity for each metal ionwas found as 4.35 mg/g (Pb(II)); 3.89 mg/g (Zn(II)) and 3.37 mg/g (Cu(II)),respectively. The solution of 0.01M EDTA was used for elution. The coefficent ofenrichment was 20. It could be absolutely seperated Pb(II), Cu(II), Zn(II) with theconcentration was 0,66 mg/L for Pb(II); 1,61 mg/L for Zn(II) and 0,93 mg/L for Cu(II)in 1.5 litre of the wastewater from that flotation mineral factorie with 2.0 gram ofmodified laterite material mass. Concentration of Pb(II), Zn(II), Cu(II) in wastewatersample was analyzed by using F - AAS.
