The primary influential factors, capacities of adsorption and desorption on the treatment of aniline-bearing wastewater using 13X zeolite synthesized from natural rock have been experimentally investigated.The results show that the ratio of adsorption reaches a plateau value when the adsorption time is 10 min.The removal rates of aniline in water is 95 %when the ratio of zeolite to wastewater is 10 g L,with the increase of pH value, the adsorption rate of aniline on zeolite decreases but reached 93 % under normal temperature.The saturation adsorbing capacities of aniline is 10 mg g, and its regularity of adsorption accords with isothermal adsorption model of Freundlich.13X zeolite can be regenerated by 20 %NaCl under 60 ℃ without noticeable loss of capacity.In fact, the results of the treatment of aniline-bearing wastewater indicate that 13X zeolite is not only able to remove aniline, but remove SS,COD_Cr,NH₃ -N and oil very efficiently .
