The batch experiments were conducted to examine the adsorption properties of Ni(II) ions by synthesizing Linde type F(K) zeolite from coal fly ash. Several important parameters were investigated. The adsorption isotherm and kinetics equation were also discussed. The results showed that, the zeolite doses had obvious effect on the adsorption properties of Ni(II). With the increasing of zeolite doses, the adsorption efficiency was improved significantly, and the saturated adsorption capacity was decreased continuously. The adsorption efficiency increased from 12% to 92% as pH increased from 2.0 to 7.0. With the increasing of temperature and contact time, the adsorption efficiency of Ni(II) ions improved obviously. Langmuir adsorption isotherm and Pseudo- first order model showed better calculation results for the adsorption of Ni(II) on Linde type F (K) zeolite.
