Sorption of selected heavy metal ions on active carbons
Języki publikacji
Abstrakty
Investigated was the sorption of heavy metals (Fe(III), Pb(II), Ni(II), Co(II) Cd(II) and Zn(II)) from aqueous solutions on carbon adsorbents which varied in surface properties. To examine the efficiency of single metal concentration on the carbon adsorbent use was made of the solid phase extraction technique. The initial carbon material was purchased from GRYFSKAND (Hajnówka, Poland). The adsorbents were processed by a variety physicochemical methods in order to change the porous structure, as well as the amount and type of the polar groups on the surface. Metal concentrations were measured by atomic absorption spectroscopy. Analysis of the sorption isotherms for heavy metals on modified active carbons suggests that the sorption process was affected by the type of the metal sorbed, by the pH of the solution, by the nature of the adsorbent surface and by the presence of other ions in aqueous solution.
