Abstract

The present paper reports the biosorption efficiency of tea residue (TR) for extermination of Pd+2 and Cd+2 ions from aqueous system using potentiometry as analytical tool. A three electrode cell setup with metal-coated gold (Au) electrode and platinum (Pt) electrode were utilized in form of working electrode for Pb+2 and Cd+2 deposition, respectively. Open circuit potential (OCP)values of metal ion concentration were observed which decreased for both heavy metals with addition of TR. Fourier transform infra-red (FTIR) spectroscopy showed the involvement of OH, C=O and C-O functional groups in the biosorbent. Scanning Electron Microscopy (SEM) analysis was carried out to study morphological features and showed the porous surface associated with biosorbent. The biosorption efficiency was analyzed to be 126 mg.g-1 for Pb+2 and 60.52 mg.g-1 for Cd+2. TR was found to be a potential biosorbent for removal of Pd+2 and Cd+2ions from aqueous solution. OCP built method offers a green approach which is uncomplicated for real time analysis of biosorption efficiency.
