What is Heavy Metals Binding Properties of Esterified Lemon about?
Sorption of Cd 2+ , Cr 3+ , Cu 2+ , Ni 2+ , Pb 2+ and Zn 2+ onto a carboxyl groups-rich material prepared from lemon was investigated in batch systems. The results revealed that the sorption is highly pH dependent. Sorption kinetic data indicated that the equilibrium was achieved in the range of 30-240 min for different metal ions and sorption kinetics followed the pseudo-second-order model for all metals studied. Relative sorption rate of various metal cations was found to be in the general order of Ni 2+ > Cd 2+ > Cu 2+ > Pb 2+ > Zn 2+ > Cr 3+ . The binding characteristics of the sorbent for heavy metal ions were analyzed under various conditions and isotherm data was accurately fitted to the Langmuir equation. The metal binding capacity order calculated from Langmuir isotherm was Pb 2+ > Cu 2+ > Ni 2+ > Cd 2+ > Zn 2+ > Cr 3+ . The mean free energy of metal sorption process calculated from Dubinin-Radushkevich parameter and the Polanyi potential was found to be in the range of 8-11 kJ mol -1 for the metals studied showing that the main mechanism governing the sorption process seems to be ion exchange. The basic thermodynamic parameters of metals ion sorption process were calculat
