Adsorption mechanism of Cd(II) by calcium-modified lignite-derived humin in aqueous solutions
Abstract Lignite-derived humin (CHM) was extracted from raw coal in Heihe City, China, producing calcium-modified lignite-derived humin (Ca-CHM) by Ca(OH)2. The physical and chemical performances of CHM and Ca-CHM were analyzed with SEM, 13C spectra and XPS techniques. The results show that Ca-CHM e...
