In recent years it has been discovered that some common use medicines, such as ibuprofen and other nonsteroidal anti-inflammatory drugs, are found in water sources in concentrations that have the potential to affect aquatic organisms. On the other hand, waste used tires are a massive problem for the environment due to the leaching of toxic compounds to soils and water. Also, the exposition to environmental conditions can make them sources of vectors like mosquitoes. In this work, three activated carbon (AC) catalysts derived from waste tire rubber, titanium dioxide and silver were synthesized using the sol–gel method. Morphological characterizations such as SEM and TEM were performed in which, the agglomeration of titanium particles and silver crystals on the surface of the AC is evident. In the XRD analysis, the presence of elemental silver nanoparticles was detected. In the diffuse reflectance spectroscopy analysis, the decrease in the titanium band gap, as well as activity in the visible spectrum, was observed. The photocatalytic tests were performed at pH 3 and 7 in the presence of UV/Vis radiation. These tests show that there are differences between the catalyst in both, UV and visible regions. Adsorption is a major phenomenon for the removal of ibuprofen, followed by photolytic decomposition. In visible spectra, the catalysts show a good performance for the removal of ibuprofen.

近年来，已经发现在水源中发现了一些常用药物，例如布洛芬和其他非甾体抗炎药，其浓度可能影响水生生物。另一方面，废旧轮胎由于有毒化合物向土壤和水中的浸出而成为环境的巨大问题。同样，暴露于环境条件会使它们成为蚊子等媒介的来源。在这项工作中，使用溶胶-凝胶法合成了三种来自废旧轮胎橡胶，二氧化钛和银的活性炭（AC）催化剂。进行了诸如SEM和TEM的形态学表征，其中在AC表面上钛颗粒和银晶体的团聚是明显的。在XRD分析中，检测到元素银纳米颗粒的存在。在漫反射光谱分析中，观察到钛带隙的减少以及可见光谱中的活性。在存在UV / Vis辐射的情况下，在pH 3和7下进行光催化测试。这些测试表明，在紫外线和可见光区域，催化剂之间都存在差异。吸附是去除布洛芬然后进行光分解的主要现象。在可见光谱中，催化剂显示出良好的去除布洛芬的性能。这些测试表明，在紫外线和可见光区域，催化剂之间都存在差异。吸附是去除布洛芬然后进行光分解的主要现象。在可见光谱中，催化剂显示出良好的去除布洛芬的性能。这些测试表明，在紫外线和可见光区域，催化剂之间都存在差异。吸附是去除布洛芬然后进行光分解的主要现象。在可见光谱中，催化剂显示出良好的去除布洛芬的性能。
