Description
Summary:The efficiency of a material based on the plant Thymus vulgaris L. for Cu(II) removal from aqueous solutions is investigated. The estimation of optimal parameters influencing the Cu(II) adsorption was studied by the batch method. Optimum pH value was found to be about 4. Kinetic of Cu(II) adsorption was very fast. Equilibrium experimental data were fitted to linear isotherm and kinetic models. It was established that the Langmuir isotherm most adequately described the adsorption process. The possibility for desorption was also studied. The results showed that the investigated biosorbent has good potential for removal of Cu(II) from contaminated wastewaters.
