Noxious effluents let out from large cum small- scale industries has led to acute adverse environmental impact over a time period. In spite of various types of pollutants present in the discharges, heavy metals have been proven to be lethal to all living organisms, whilst exceeding the tolerance levels. In this regard, their confiscation has become inevitable by adoption of varied suitable methodologies. The current inquest is engrossed on probing the efficiency of an eco-derived material, Magnolia champaca Barks (MCB) to trap Zn(II) / Cd(II) ions from laboratory aqueous medium. This ecofriendly material is acid treated (TMCB), so as to improve its surface nature, evidently favoured by microscopic image study. Fourier Transformation Infra-Red and Scanning Electron Microscopy / Energy Dispersive X-Ray Analysis spectra are recorded for sorbent characterization. The factors which influence the sorptive effectiveness of TMCB include particle sizes, initial concentrations of the sorbate molecules, agitation time frames, dosages, pH values and temperatures. The concentrations of divalent ions in the pre and post run samples are assessed using Atomic Absorption Spectrophotometer. Maximum chelation of 98% Zn(II) and 96% Cd(II) had occurred under aligned parametric conditions, with variations in dosage, concentration and contact time interval. The aforementioned observations support the promising nature of the identified bark to adsorb toxic metal species.
