| dc.description.resumo | Adsorption of Cu (II) ions using carnauba straw powder (CSP) as biosorbent was studied in batch experiments. The adsorption process was evaluated considering copper solution concentration and pH, biosorbent size and dosage, adsorption time, and temperature. The best results were obtained at pH 6 and 10 g/L of biosorbent. A decrease in cupric ion uptake was observed with the increase of Cu (II) concentration. The Cu (II) removal capacity was improved with the reduction of the biosorbent granule size. Adsorption data were well fitted by the Langmuir isotherm and pseudo-second order kinetic model. The process was both spontaneous and exothermic. Best adsorption results were obtained at 50 °C, reaching 9.5 mg Cu (II)/g biosorbent | pt_BR |
