研究了磁改性沸石（MMZ）吸附和磁分离对稀释溶液中铅离子的去除作用。采用合成沸石粉作为重金属离子吸附剂，氧化铁粉作为磁性载体材料。通过磁化测量发现，制备的MMZ既保留了母体沸石的吸附能力，又保持了其结构的完整性。这些发现表明，MMZ可以用于去除废物中的重金属离子。
The removal of Pb ion from diluted solutions by sorption onto magnetically modified zeolite (MMZ) and magnetic separation, was studied at laboratory scale. Synthetic zeolite fines were used as heavy metal ion sorbent, while iron oxide fines were used as magnetic carrier materials. The as-prepared MMZ, characterized by magnetization measurements, were found to retain the adsorption capacity of the parent zeolite as well as its structural integrity. These findings show that MMZ can be used for the removal of heavy metal ions from waste.
