A theoretical overview of heavy metal treatment with agricultural wastes

Abstract

Tomato plant between Pb 2+,Cd 2+ with tomato waste having amino and the other functional groups waste contain cellulose materials(lignin), polysaccarides having functional groups having the ability of binding heavy metals as sorbents is commonly cultivated plant for its fruits. Aim of this study to determine the best alternative way to search the binding capacity of agriculturel waste as theoretical to remove heavy metals with tomato plant from waste waters as economically by comparing experimental results respectively. The capacities of adsorbtion for heavy metals (Pb(II), Cu(II) and Cd(II)) of the tomato plant residue were 19.06, 33.87 and 26.76 mg/g sorbent. As theoretical, HF (Hartree-fock), lanl2dz methods were used for moleculer calculation. The theoretical calculations were carried out by means of the lanl2dz functional base. The chemical activities were calculated by using this method. The removal of Pb 2+ and Cd 2+ found lower than Cu 2+ because of the strong complex formation as experimental and theoretical calculations supported this issue. Theoretical calculations important to prevent loss of time and cost.
