Waste Water Bioremediation Using Natural Combination Of Leaves
Publication Date : 08/04/2019
Industrial as well as domestic waste water contains heavy metals which are hazardous above a certain limit. Heavy metal pollution results from industrial activities and many a times, they are directly discharged into the main streams and rivers. These heavy metals cause nature degradation, represent a major loss of non-renewable resources and pose a huge problem in health and ecology. Bioremediation through adsorption on biomass has attracted many researchers as it is cost effective and efficient. In the present study, removal of Copper and Zinc metal ions has been evaluated by adsorption on natural combination of leaves. The variation in metal ion concentrations after and before adsorption was analyzed by using Atomic Absorption Spectrophotometer. Experimental data showed maximum removal efficiency of Copper ions to be 86.28% by Tulsi and Methi leaves combination after 1 day of contact period. The maximum uptake of Zinc ions, 82.47%, showed by Custard Apple and Eucalyptus leaves combination. All the three combinations viz. Calotropis Procera-Tulsi, Custard Apple-Tulsi and Custard Apple-Eucalyptus showed good results for Zinc ions as the removal efficiencies ranges 71-82%. The results from this study indicate that using combination of leaves as an adsorbent may be an efficient and economic means for removing heavy metals ions from aqueous solutions.
