Tóm tắt

The adsorption of Cu(II) ion from aqueous solutions using potato peels charcoal, which are normally discarded as solid waste was investigated. The study on influence of various parameters such as solid liquid ratios, solution concentration, temperature and pH was carried out. The adsorption yield of 98.5 percent was reached at pH 6 and Cu(II) solution concentration 190 mg/l. The copper adsorption was found to follow the Langmuir and Freundlich isotherms. The maximum adsorption capacity of potato peels charcoal of 53.9 mg/g was determined from Langmuir isotherm equation.
