In this work, the degradation of a mixture of nine pharmaceuticals was performed in near environmental concentrations (500 µg L^-1) using hospital wastewater as the matrix and employing as a coupling strategy solar photo-Fenton (SPF) treatment followed by adsorption. Different SPF approaches were studied. The best condition chosen for the degradation of the pharmaceuticals by SPF was that which used an initial concentration of H₂O₂ of 100 mg L^-1and multiple additions of Fe²⁺ of 5 mg L^-1 at times of t = 0, 5, and 10 min in hospital wastewater. Degradation of 80% was obtained for Fluconazole, whereas the degradation of other pharmaceuticals achieved 99% of primary elimination. Consequently, 38 Transformation Products (TPs) were generated by the SPF process. The combination of SPF with the adsorption process using avocado seed activated carbon (ASAC) as sorbent was used to prevent TPs reaching the aqueous environment. For this reason, the SPF process was stopped after 15 min; and within this time, the largest number of TPs (28 TPs) was observed. A volume of 20 mL of HWW previously treated by SPF was combined with 14 mg ASAC, for 15 min of contact time. This coupling removed 30 of the 36 compounds (remaining pharmaceuticals and TPs), with an open-chain and highly polar TPs having a 50 and 60% removal for FLT TP2 and FLT TP3, respectively. With respect to compounds that present aromatic rings, these presented a 98 to 100% removal rate in the coupled processes, with π–π interactions as the main interaction mechanisms with ASAC.

在这项工作中，将九种药物的混合物在接近环境浓度（500  µg  L ^-1）的条件下进行降解，采用医院废水作为基质，并采用太阳光芬顿（SPF）处理作为吸附策略，然后进行吸附。研究了不同的SPF方法。选择SPF降解药物的最佳条件是使用初始浓度为100 mg L ^-1的H ₂ O ₂，并在t = 0时多次添加5 mg L ^-1的Fe ²⁺， 5和10     分钟在医院废水中。氟康唑的降解率为80％，而其他药物的降解则达到了99％的基本消除率。因此，通过SPF流程生成了38个转换产品（TP）。SPF与鳄梨种子活性炭（ASAC）作为吸附剂的吸附过程相结合，可防止TP到达水性环境。因此，SPF过程在15 分钟后停止；在这段时间内，观察到最大数量的TP（28个TP）。 用SPF预先处理的20毫升HWW与14 毫克ASAC合并，用于15 接触时间的最短时间。这种偶联去除了36种化合物中的30种（剩余药物和TPs），其中开链和高极性TPs对FLT TP2和FLT TP3的去除率分别为50％和60％。对于存在芳环的化合物，这些化合物在偶联过程中的去除率达到98％至100％，其中π-π相互作用是与ASAC的主要相互作用机理。
