4A zeolite was prepared by using calcination and hydrothermal method with weathered granite sand tail mud as silicon and aluminum sources. The optimal calcination temperature was determined to be 600℃. Based on the single-factor experiment, in terms of cation exchange capacity, according to the experimental design principle of central composite, NaO2/SiO2, H2O/NaO2, crystallization temperature and crystallization time were all optimized. The optimum parameters were determined to be Na2O/SiO2=1.42, H2O/Na2O=61.00, crystallization temperature of 90.89℃, and crystallization time of 8.16 h. The corresponding optimum was 198.50 mmol/100 g. The as-obtained 4A zeolite was characterized by using scanning electron microscopy and X-ray diffraction, indicating that it was highly crystallized. The removal mechanism of NH4+-N from the solutions with the 4A zeolite was attributed to the ion exchange and NH4+-N adsorption on the 4A zeolite, which could be well described with the pseudo-second-order kinetic model and the Langmuir model. In addition, the maximum adsorption capacity to NH4+-N was calculated to be 102.04 mg/g. Therefore, this 4A zeolite could be used as highly efficient adsorbents to remove NH4+-N from water.
