| Abstract: | Performance and kinetic behavior of adsorption of NH3 in wastewater on fly ash from a coal-fired power plant were studied compared with that on activated carbon.The static adsorption experiment showed that both Bangharm and the modified Elovich equations can be used to well describe the kinetic behavior of adsorption,and from the equations it was derived that the maximum adsorption capacity was reached when the reaction lasted for 930min.Meanwhile,the comparative study indicated that adsorption capacity of ... |
