چکیده
The removal of copper (II), zinc (II), and chromium (III) from wastewater by carrot residues
(CR) was investigated to evaluate cation exchange capacity. The effects of solution pH and co- ions were
studied in batch experiments. Adsorption equilibria were initially rapidly established, and then decreased
markedly after 10 min. Column experiments were carried out in a glass column filled with CR to
evaluate the metal removal capacity. The influences of the feed concentration and feed rate were also
studied in order to compare the dynamic capacity for metal binding in different feed concentrations.
