摘要: In this paper, Cu2+ was absorbed by the carboxylated bagasse hemicellulose, and the thermodynamics have been studied. Thermodynamics analysis shows that the adsorption of Cu2+ fits the Freundlich isothermal adsorption model very well. It can be seen from the model that Delta H < 0 and Delta G < 0, which means that the absorption was exothermic and spontaneous, respectively.
