Abstract :
In-situ experiments were conducted to study the adsorption isotherms of ClO4- and NO3- onto 6 kinds of activated carbon(25°C). The results shows adsorption capacity of GAC is bigger than PAC, and may have some relationship with the iodine value of carbon. Competition adsorption exists between NO3- and ClO4-. At NO3-:ClO4- = 5:1(mass ratio) in double component adsorption experiment, adsorption capacity of ClO4- decreased by 37.5~56.5% compared with single component system. Then adsorption capacity decreased little after increasing more NO3- ratio.
