高岭土对染料废水中亚甲基蓝的吸附去除
Adsorption and Removal of Methylene Blue in Dyeing Wastewater by Kaoline
摘要
Abstract
Adsorption and removal of methylene blue in dyeing wastewater is studied by using natural silicate material kaoline.The effect of kaoline on adsorption and removal of methylene blue is investigated by equilibrium adsorption method with different kaoline dosage and initial pH Value.The thermodynamic and kinetic adsorption are further investigated and the optimum experimental conditions are determined.The results show that the optimal dosage of kaoline is 0.8 g/L.Adsorption capacity of kaoline to methylene blue increases with the increasing of the initial pH value of methylene blue.Thermodynamic studies show that the Koble-Corrigan model is the best suitable for the adsorption process,which is more suitable for the adsorption behavior of kaoline on methylene blue,and the adsorption process is a spontaneous endothermic process.Kinetic studies show that the adsorption equihbrium reaches at 60 min,which indicates that adsorption process is in accordance with the quasi two stage kinetic model.关键词
