The dispersion of pollutants in the aquatic environment is an emerging health concern worldwide. In this sense, it is essential to develop new materials that can improve the treatment quality of both water and wastewater. The present study has demonstrated evidence of the applicability of recyclable glass-ceramic materials for the efficient photocatalytic treatment of real surface water and textile industry wastewater. Two glass compositions containing TiO₂ or ZnO-TiO₂ have been investigated. The studied materials exhibited good performance in terms of humic acid and COD removal from raw surface water and textile industry wastewater, respectively. However, ZnO-TiO₂ glass-ceramic photocatalyst was the best photocatalyst with maximum efficiency of 53% HA removal from surface water and 75% decolorization (or 60% COD removal) of wastewater. What is more, the reusability tests confirmed a minor variation (<4%) in the photocatalytic efficacy for three consecutive usages. Therefore, the prepared materials are suitable for the applications in which reusability is an important key factor such as water and wastewater decontamination.

紫外敏感 ZnO 和 TiO2-ZnO 纳米晶透明微晶玻璃材料用于地表水和纺织工业废水的光催化净化

污染物在水生环境中的扩散是世界范围内一个新兴的健康问题。从这个意义上说，开发能够改善水和废水处理质量的新材料至关重要。本研究证明了可回收微晶玻璃材料在有效光催化处理真实地表水和纺织工业废水中的适用性。已经研究了包含TiO ₂或ZnO-TiO _{2 的}两种玻璃组合物。研究的材料分别在原地表水和纺织工业废水中去除腐殖酸和 COD 方面表现出良好的性能。然而，ZnO-TiO ₂微晶玻璃光催化剂是最好的光催化剂，其最大效率为从地表水中去除 53% 的 HA 和对废水 75% 的脱色（或 60% 的 COD 去除）。更重要的是，可重复使用性测试证实了连续三次使用光催化效率的微小变化（<4%）。因此，所制备的材料适用于可重复使用性是重要关键因素的应用，例如水和废水净化。
