R. of Iran Journal Article 2003 06 09 The removal of copper (II), zinc (II), and chromium (III) from wastewater by carrot residues<br />(CR) was investigated to evaluate cation exchange capacity. The effects of solution pH and co- ions were<br />studied in batch experiments. Adsorption equilibria were initially rapidly established, and then decreased<br />markedly after 10 min. Column experiments were carried out in a glass column filled with CR to<br />evaluate the metal removal capacity. The influences of the feed concentration and feed rate were also<br />studied in order to compare the dynamic capacity for metal binding in different feed concentrations. https://ijsts.shirazu.ac.ir/article_2848_531bd71482c753f9535d5a5bb2c8c04f.pdf
