Sorption of chromium (VI) by spent grain under batch conditions

Sorption of chromium (VI) by spent grain under batch conditions

Batch experiments were performed to evaluate the ability of spent grain to remove chromium (VI) from aqueous solution. Parameters investigated include pH, contact time, sorbent dosage, agitation rate, and the presence of other anions. Application of the Langmuir isotherm to the Cr(VI)–spent grain sy...
