Abstract
The aim of the work was to establish the possibility of using dwarf everlast (Helichrysum arenarium) as a natural sorbent for the removal of cadmium and lead ions. The research carried out allowed to select nonlinear equilibrium and kinetic models. Additionally conducted experiments enabled to perform tests for metal ions recovery from the surface of the sorbent. The material had a sorption capacity equal to 80.1 mg/g for lead ions and 23.3 mg/g for cadmium ions. The Freundlich isotherm model has the best fit for the lead ion sorption, while cadmium sorption is best described by the Temkin, Freundlich and Langmuir isotherm models. The kinetic experiments showed that process is of chemical nature and that the course of sorption is in accordance with the Elovich model for both chosen elements. Desorption studies confirmed the possibility of recovery of cadmium and lead ions at a level of ~76% and ~85% using acetic acid, respectively.
