Comprehensive Utilization of Agricultural Bean Husk Powder (CA) Beads – The Research and Application of Using Immobilized Method to Adsorb and Purify Lead of Mine Wastewater

Abstract:

In this study, calcium alginate immobilized bean husk powder(CA) beads was used as an adsorbent for the aim of removing Pb(Ⅱ) ions form the aqueous solutions, and the effect of initial solution pH, contact time, temperature, initial metal ion concentrations and ionic strength in the adsorption process were investigated in detail. Experimental results showed that the amount of adsorbed Pb(Ⅱ) increased with the increasing initial metal ion concentration and solution pH in the examined range. The results showed that the optimum adsorption pH for Pb(Ⅱ) was5.5, the uptake was 10. 78 mg/g, the desorption rates of Pb(Ⅱ) by EDTA was calculated as 90 %. The concentration of Pb(Ⅱ)of mine wastewater reach the first class of irrigation water quality standards after the first time of adsorption treatment, and reach the first class of fishery water quality standard after the second treatment.
