In this study, the performance of three commercial available monolithic carbonaceous aerogels (NQ30A, NQ60A and NQ80A) for the removal of different emerging pollutants, detected in water sources, was evaluated. More specifically, the removal of two pharmaceuticals (antipyrine and sulfamethoxazole) and an anti-fungal agent (methyl paraben), widely used in cosmetics, was studied. The NQ60A demonstrated the best adsorption characteristics and effectively adsorbed over 50 mg/g of the antipyrine and around 30 mg/g sulfamethoxazole and methyl paraben. The kinetic study of the adsorption process revealed that pseudo-first order kinetic model described very well the kinetic behaviour of the selected pollutants onto the NQ60A aerogel. After that, the regeneration of the loaded aerogel, with antipyrine alone and in presence of the other two contaminants, was evaluated. The regeneration was accomplished in two ways: (1) by using directly the loaded aerogels as cathode during the electro-Fenton treatment and (2) by its regeneration immersed in the bulk volume of electro-Fenton cell (boron doped diamond as anode and carbon felt as cathode). Both approaches can provide an effective removal of the pollutants inside the aerogel. In addition, the regenerated aerogel proved to maintain its adsorptive properties and can be successfully reused in successive cycles of adsorption-regeneration. On the basis of these promising results, it can be concluded that the proposed strategy based on aerogels adsorption and electro-Fenton regeneration is a suitable alternative for emerging pollutants removal from water streams.

整体式碳质气凝胶在环境中的应用，用于去除新兴污染物。

在这项研究中，评估了三种市售的整体式碳质气凝胶（NQ30A，NQ60A和NQ80A）在去除水中检测到的各种新兴污染物方面的性能。更具体地说，研究了去除化妆品中广泛使用的两种药物（安替比林和磺胺甲恶唑）和抗真菌剂（对羟基苯甲酸甲酯）的方法。NQ60A表现出最佳的吸附特性，可以有效地吸附超过50 mg / g的安替比林和约30 mg / g的磺胺甲恶唑和对羟基苯甲酸甲酯。吸附过程的动力学研究表明，拟一级动力学模型很好地描述了所选污染物在NQ60A气凝胶上的动力学行为。此后，仅使用安替比林并在存在其他两种污染物的情况下对负载的气凝胶进行再生，被评估。再生通过两种方式完成：（1）在电子芬顿处理过程中直接使用负载的气凝胶作为阴极；（2）通过将其浸没在电子芬顿电池的主体体积中（硼掺杂的金刚石作为阳极和碳）进行再生感觉是阴极）。两种方法都可以有效去除气凝胶内部的污染物。此外，再生气凝胶被证明可以保持其吸附性能，并可以在连续的吸附-再生循环中成功使用。基于这些有希望的结果，可以得出结论，基于气凝胶吸附和电子芬顿再生的拟议策略是从水中去除新兴污染物的合适替代方法。（1）在电子芬顿处理过程中直接使用负载的气凝胶作为阴极，（2）通过将其再生浸入电子芬顿电池的体积中（掺硼的金刚石作为阳极，碳毡作为阴极）。两种方法都可以有效去除气凝胶内部的污染物。此外，再生气凝胶被证明可以保持其吸附性能，并可以在连续的吸附-再生循环中成功使用。基于这些有希望的结果，可以得出结论，基于气凝胶吸附和电子芬顿再生的拟议策略是从水中去除新兴污染物的合适替代方法。（1）在电子芬顿处理过程中直接使用负载的气凝胶作为阴极，（2）通过将其再生浸入电子芬顿电池的体积中（掺硼的金刚石作为阳极，碳毡作为阴极）。两种方法都可以有效去除气凝胶内部的污染物。此外，再生气凝胶被证明可以保持其吸附性能，并可以在连续的吸附-再生循环中成功使用。基于这些有希望的结果，可以得出结论，基于气凝胶吸附和电子芬顿再生的拟议策略是从水中去除新兴污染物的合适替代方法。
