The objective of the present study is the characterization of an adsorbent plant material based on Hypericum perforatum L. and the investigation of its feasibility for the removal of Cu2+ ions from aqueous solutions. XRD, TGA, FTIR, SEM and low-temperature nitrogen adsorption were used for the analytical characterization of the material. Particle s...

... the coefficient of correlation r 2 for the DubininRadushkevich model is the highest from all the models applied and the saturation/maximum capacity seems to be reached (Fig. 6),the equilibrium adsorption capacity was calculated from the Dubinin-Radushkevich isotherm model and it was found to be 16.94 mg g -1 for HP. This adsorption capacity is compared with those reported in the literature 10,[17][18][19][20][21][22] (Table 2). It is evident that the material HP displays reasonably good adsorption capacity for Cu(II) and it could be used as potential adsorbent for the effective removal of these ions from contaminated aqueous solutions. ...
