| Abstract: | Ultrasonic treatment of Xanthoceras Sorbifolia Bunge husk activated carbon(XSBHAC) developed by zinc chloride solution activation and their adosorption of Methylene Blue(MB) have been investigated.Experiments were carried out as function of contacting time,pH and temperature.The results showed that adsorption of activated carbon fitted well with the Langmuir isotherm.The Langmuir monolayer saturation capacities of MB adsorbed onto activated carbon(AC) were 235.041,279.985 and 287.307 mg·g-1 at 30,40 and 50 ℃,respectively;the rate of adsorption was found to conform to the pseudo-second-order kinetics with good correlation;various thermodynamic parameters had been calculated,and the thermodynamics parameters of system indicated a spontaneous and endothermic process. |
