We synthesized the TiO_2-zeolite composites and applied them to the removal of sulfamethazine (SMT) in secondary effluent. The SMT was selectively adsorbed onto high-silica Y-type zeolite in the composites. Resultantly, the inhibitory effect of the coexisting materials was reduced, and the composites could remove SMT more effectively compared with TiO_2 alone in the secondary effluent. We also synthesized magnetic particle containing TiO_2-Zeolite composite catalyst, and confirmed the recovery of the composites by a magnet, sufficient adsorption capacity equivalent to the HSZ-385, and photocatalytic decomposition of SMT under simulated solar light. Through these results, we evaluated the treatment performance of SMT by the developed composites.

合成了TiO_2-沸石复合材料，并将其应用于二级出水中磺胺二甲嘧啶（SMT）的去除。SMT被选择性地吸附到复合材料中的高硅Y型沸石上。结果表明，与单独使用TiO_2相比，复合材料对二级出水中SMT的去除效果更好。我们还合成了含磁性颗粒的TiO_2-沸石复合催化剂，并证实了该复合催化剂的磁铁回收率、与HSZ-385相当的足够吸附容量以及在模拟太阳光下对SMT的光催化分解。通过这些结果，我们评估了SMT的处理性能的开发的复合材料。
