Cation-removal capacity of the ashes was analyzed by potentiometric titration. It was found that the capacity of wood ash was two times higher (37.3 meq g-1) than bone ash (15.2 meq g-1). Kinetics of metal ions removal by both ashes was described with pseudo-second order equation and Langmuir model was employed to describe equilibrium of the process. Wood ash had better removal properties than bone ash - at the same experimental conditions biosorption capacity at equilibrium for wood ash was 2 times higher (244 mg g-1) than for bone ash (123 mg g-1). Promising results were also obtained for wood ash, which was capable of removing 67.9 % of Zn(II) ions, 70.4 % of Cd(II) ions, 92.8 % of Cu(II) ions and 99.1 % of Cr(III) ions from model solution of wastewater from metallurgical industry and 84.5 % of Cr(III) ions from the postbiosorption solution from the production process of biological feed additives. The utilization of ashes of biological origin was found to be a promising alternative to conventional processes of wastewater treatment. </p></abstract><publication_date><month>04</month><day>30</day><year>2013</year></publication_date><pages><first_page>205</first_page><last_page>217</last_page></pages><publisher_item><identifier id_type="pii">582</identifier></publisher_item><doi_data><doi>10.30955/gnj.000582</doi><timestamp>1713596525</timestamp><resource>https://journal.gnest.org/publication/582</resource></doi_data></journal_article></journal></body></doi_batch> </div>
