Abstract :
Adsorption behavior of chitosan composite fly ash (CCF) in adsorption of reactive brilliant blue wastewater were investigated. CCF was characterized by means of SEM and FTIR. Results showed that particle size of CCF is about 2-15μm. The isothermal adsorption follows the isothermal adsorption model of Langmuir. Enthalpy change at adsorption temperatures in range of 288-318K is -21.97 kJ mol-1, which suggests that adsorption process is endothermic. The adsoption kinetics were well described by pseudo-second-order kinetic model and activity energy is 65.65kJ mol-1, indicating the main adsorption mechanism of chemical adsorption.
