Summary: The present article reviews the treatment of pharmaceutical contaminants, such as ibuprofen and ciprofloxacin, in water using graphene-based materials. Three methods, adsorption, photocatalytic degradation, and electro-fenton reactions, are discussed in detail, along with their optimal operating conditions. The study found that graphene-derived adsorbents demonstrated complete removal of ibuprofen from wastewater at pH 7 for 60 minutes, and a 99% uptake of ciprofloxacin was achieved with graphene nanoplates/boron nitrate aerogel at pH 7 for 60 minutes. Additionally, the article highlights the future perspectives and research gaps in the application of graphene-based materials.

Summary: The development of efficient sonocatalysts is essential for treating antibiotic wastewater. In this study, an S-scheme sonocatalyst Cu2O/BiFeO3 was synthesized, where Cu2O nanoparticles were grown on the surface of BiFeO3. The Cu2O/BiFeO3 showed superior sonocatalytic performance for the degradation of tetracycline compared to pure BiFeO3. The improved performance can be attributed to the S-scheme charge transfer mechanism between Cu2O and BiFeO3, which inhibits electron-hole recombination and promotes carrier transfer.

Summary: Precisely engineering the morphology and regulating the hybrid interface of each component in a heterojunction are crucial for enhancing charge carrier separation. The Z-scheme heterojunction of flower-like bismuth oxycarbonate/bismuth oxybromide prepared in this study exhibited a high photocatalytic activity, attributed to the hybrid mode of BOC and BiOBr, and the Z scheme electron transfer path and oxygen vacancies present in BOC/BiOBr.

Summary: This study evaluated the application of a new carbon-based material modified with Ru-Nb oxides for H2O2 generation and CPF degradation. The best-modified material, 5.0% Ru05Nb95O/C, achieved approximately 100% CPF degradation and 60% removal of total organic carbon. Higher current densities and longer degradation times resulted in nearly 100% total carbon removal. A stochastic model for predicting organic matter removal time was proposed and confirmed.

Summary: In order to fulfill the Paris Agreement, CO2 capture technologies must be developed to reduce Green House Gas emissions. Adsorption is considered a viable technology due to its mild conditions. Selective sorbents with high CO2 adsorption capacities are needed. This study used branched poly-ethylenimines (PEI) with different average molecular weights, agglomerated with silica at different weight percentages. Adsorption was measured and kinetic parameters were estimated. The results showed that the materials produced were selective and had potential use in adsorption processes, with the sample of the lowest average molecular weight having the highest adsorption capacity.

Summary: This study investigates the removal of the antibiotic ciprofloxacin using four iron and nickel-based catalysts from different sewage sludge. The results show that the source of the sewage sludge and the activating agent used have a significant influence on the physicochemical properties and catalytic activity of the materials. The use of iron chloride solely as activating agent achieves the highest ciprofloxacin removal and lower iron leaching concentration.

Summary: Environmental legislation and potential nutrient recovery drive the adoption of advanced treatment technologies for biosolids waste management. This study focused on phosphorus recovery from sewage sludge using wet oxidation. The wet oxidation process achieved high removal of organic matter (up to 85% COD) and total solids (up to 75%) at elevated temperature and pressure. Both liquid and solid fractions contained high amounts of phosphorus that can be recovered. Phosphorus was successfully recovered from the liquid effluent through chemical precipitation as struvite, with a recovery rate exceeding 95%. Acid leaching of the solid fraction resulted in a phosphorus recovery rate of up to 60%, with all extracted phosphorus in the form of orthophosphate.

Summary: This study explores the use of green solvents and terpene-based eutectic solvents for the removal of azole fungicides from aqueous environments. The solvent carvacrol is found to have the best extraction performance, achieving an extraction efficiency of over 97.88%. Moreover, it can be reused multiple times with minimal loss of extraction effectiveness. Carvacrol is thus proposed as a sustainable solvent for the extraction of azole fungicides.

Summary: In this study, sewage sludge-derived activated carbon loaded with iron nanoparticles (FeSAC) exhibited highly effective catalytic activity in the degradation of the antibiotic ciprofloxacin through the CWAO reaction. The properties of the FeSAC catalyst were characterized using various techniques. The CWAO reaction was evaluated under different conditions, and temperature and catalyst dosage were found to significantly impact the removal of the antibiotic. A potential equation was proposed to describe the degradation of ciprofloxacin, and Density Functional Theory calculations were performed to understand the degradation mechanism. The synthesized catalyst showed high stability and potential for application in environmentally-relevant matrices at a low treatment cost.
