This work presents the main results regarding the use of solar heterogeneous photocatalysis with TiO₂ on the removal of Benzophenone-1 and Benzophenone-2 (BP1 and BP2) in aqueous samples at lab and pilot scale. BP1 and BP2 are two UV-filters that have been classified as potential endocrine disruptors, and their presence in water has been reported by different researches. Experiments were conducted at lab scale using simulated sunlight radiation, while at pilot scale a solar compound cylinder-parabolic (CCP) collector and direct sunlight were employed. Effects of catalyst concentration and solution pH on contaminants elimination were assessed. Pollutants were completely removed at lab conditions in just 60 min of reaction, while under pilot scale tests elimination was around 90.0% in 360 min. Mineralization of treated samples was around 60%. In general, it was found that the photo-generation of hydroxyl (HO·) radicals contributes to BP1 and BP2 removal, and that higher doses of TiO₂ could have an inhibitory effect. Additionally, presence of some inorganic ions on the aqueous matrix (drinking water) used in the pilot-scale tests would be associated to a reduction on the extent of pollutants degradation, which together with aspects such as the type of reactor and the atmospheric and climate conditions would limit the process efficiency in comparison with results at lab-scale experiments.

这项工作提出了关于使用TiO ₂进行太阳能非均相光催化的主要结果实验室和中试规模的水性样品中苯甲酮-1和苯甲酮-2（BP1和BP2）的去除方法 BP1和BP2是已被分类为潜在内分泌干扰物的两种紫外线过滤剂，不同研究已经报道了它们在水中的存在。实验是在实验室规模下使用模拟的日光辐射进行的，而在中试规模下则采用了太阳能复合圆柱抛物线（CCP）收集器和直射阳光。评估了催化剂浓度和溶液pH值对污染物去除的影响。在实验室条件下仅反应60分钟即可完全去除污染物，而在中试规模的测试中，在360分钟内消除率为90.0％。处理过的样品的矿化度约为60％。一般来说，₂可能有抑制作用。此外，在中试规模测试中使用的水基体（饮用水）上存在一些无机离子将与污染物降解程度的降低有关，这与诸如反应器类型以及大气和气候等方面有关与实验室规模的实验结果相比，这些条件将限制过程效率。
