Synthetic magnetic zeolite with Fe₃O₄ was developed and its adsorption performance of ammonium ions was examined. The influence of pH levels, Fe₃O₄ content of the magnetic zeolite, magnetization curve of the magnetic zeolite and isotherm curve were examined in batch type experiments. Magnetic zeolite synthesized by a hydrothermal process was observed with less than 12.6 wt% of Fe₃O₄ content by scanning electron microscope (SEM) and X-ray diffraction (XRD) analysis. With the optimum pH level around 8, q_e decreases linearly with the increase of Fe₃O₄ content. Additionally, the adsorption isotherm of ammonium ions is approximated by a Langmuir equation when the maximum adsorption was obtained at about 1.60 mmolg⁻¹. Such processes as the substitution and thermal desorption methods were successfully introduced to regenerate the magnetic zeolite saturated by ammonium ions, which is shown to be easily separated by magnetic force. Thus, the magnetic zeolite is a potential adsorbent for the removal of ammonium ions with an easy separation method using a magnetic process.

研制了具有Fe ₃ O _4的合成磁性沸石，并研究了其对铵离子的吸附性能。在间歇式实验中，考察了pH值，电磁沸石的Fe ₃ O ₄含量，电磁沸石的磁化曲线和等温线的影响。通过扫描电子显微镜（SEM）和X射线衍射（XRD）分析观察到通过水热法合成的电磁沸石具有小于12.6wt％的Fe ₃ O ₄含量。在最佳pH值约为8的情况下，q _e随着Fe ₃ O ₄的增加而线性下降。内容。另外，当在约1.60mmolg ^-1处获得最大吸附时，通过Langmuir方程来近似铵离子的吸附等温线。成功地引入了诸如置换和热解吸方法之类的过程来再生被铵离子饱和的磁性沸石，该铵离子显示出容易被磁力分离。因此，磁性沸石是用于通过使用磁性方法的容易的分离方法去除铵离子的潜在吸附剂。
