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.

我们合成了TiO_2-沸石复合材料并将其应用于二级出水中磺胺二甲嗪(SMT)的去除。 SMT选择性地吸附在复合材料中的高硅Y型沸石上。结果表明，共存材料的抑制作用减弱，与单独使用TiO_2相比，复合材料能够更有效地去除二级出水中的SMT。我们还合成了含有TiO_2-沸石复合催化剂的磁性颗粒，并证实了复合材料的磁体回收、与HSZ-385相当的足够吸附能力以及模拟太阳光下SMT的光催化分解。通过这些结果，我们评估了所开发的复合材料的 SMT 处理性能。
