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.

以风化花岗岩洗砂尾泥为硅铝源,通过水热法制备4A沸石用于处理氨氮污染。通过不同煅烧温度的表征确定尾泥活化最佳温度为600℃,并在单因素实验基础上,以阳离子交换容量(CEC)为响应值,根据中心组合设计-响应面优化法实验设计原理对水钠比、钠硅比、晶化温度、晶化时间等参数进行优化,发现晶化时间对阳离子交换容量影响最大,确定最优工艺参数为:n(H2O):n(NaO2)=1.42;n(NaO2):n(SiO2)=61.0;晶化温度为90.89℃;晶化时间为8.16 h,此时阳离子交换容量最大为198.5 mmol/100 g。用扫描电子显微镜、X射线衍射对合成4A沸石进行表征,最优工艺参数下所得4A沸石纯度较高。静态吸附实验,pH=4,固液比为0.5 g/L,氨氮浓度为70 mg/L,结果表明:以风化花岗岩洗砂尾泥合成的4A沸石对氨氮吸附量为69.1 mg/g,对氨氮去除机理主要为离子交换,符合二级反应动力学,是一种潜在的氨氮高效吸附材料。

以风化花岗岩洗砂尾泥为硅铝源,通过水热法制备4A沸石用于处理氨氮污染。通过不同煅烧温度的表征确定尾泥活化最佳温度为600℃,并在单因素实验基础上,以阳离子交换容量(CEC)为响应值,根据中心组合设计-响应面优化法实验设计原理对水钠比、钠硅比、晶化温度、晶化时间等参数进行优化,发现晶化时间对阳离子交换容量影响最大,确定最优工艺参数为:n(H2O):n(NaO2)=1.42;n(NaO2):n(SiO2)=61.0;晶化温度为90.89℃;晶化时间为8.16 h,此时阳离子交换容量最大为198.5 mmol/100 g。用扫描电子显微镜、X射线衍射对合成4A沸石进行表征,最优工艺参数下所得4A沸石纯度较高。静态吸附实验,pH=4,固液比为0.5 g/L,氨氮浓度为70 mg/L,结果表明:以风化花岗岩洗砂尾泥合成的4A沸石对氨氮吸附量为69.1 mg/g,对氨氮去除机理主要为离子交换,符合二级反应动力学,是一种潜在的氨氮高效吸附材料。

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.
