Abstract
The efficiency of natural sepiolite for the removal of Cu2+ and Co2+ ions
from aqueous solution was determined using the batch method. The sorption
experiments were performed as a function of the initial metal concentration,
the equilibration time and temperature. Thermodynamic parameters, such as
enthalpy, free energy and entropy, were calculated from the temperature
dependent sorption isotherms and these values showed that the sorption of the
investigated metals onto sepiolite was endothermic. The pseudo-second order
kinetic model provides the best correlation of the experimental kinetic data.
