Therefore, this study investigates the efficiency of using colloidal activated carbon (CAC) for the removal of lamotrigine in the lab. The adsorption performance of the CAC for lamotrigine under different operational parameters was evaluated through a series of fixed-bed columns packed with sand and CAC, mimicking a subsurface environment. Breakthrough curves were plotted, and the effect of various factors on lamotrigine removal, including flow rate, CAC dosage, inlet concentration, and background ions, was assessed. Physiochemical characterizations revealed that the CAC is negatively charged, exhibits a microporous structure with a high BET surface area of 1160 m<sup>2</sup>/g, and is rich in oxygen functional groups. The experimental breakthrough curves were fitted using various models, with the Dose-Response model being the best fit. Lamotrigine was effectively removed by the CAC with a maximum adsorption capacity of 5.76 mg. g-1 at 1 mL/min flowrate, 20 mg/L inlet concentration, 20 cm bed length and 0.6 g CAC dosage. The maximum removal efficiency of lamotrigine was 65 % at a flow rate of 0.5 mL/min. The removal efficiency was found to increase with increasing CAC dosage and decreasing both Lamotrigine initial concentrations and flow rate.

This study evaluated the independent and combined effects of the redox mediator anthraquinone-2-sulfonate (AQS) and controlled microaeration on LAS biodegradation in upflow anaerobic sludge blanket (UASB) reactors. Two reactors treating synthetic wastewater containing 15 mg L<sup>−1</sup> LAS were operated for 90 days: R1, a strictly anaerobic UASB, and R2, a micro-aerated UASB. Each reactor was assessed without (Period I) and with AQS addition (50 μM, Period II). Under strictly anaerobic conditions without AQS, LAS removal was low and highly unstable (32 ± 16%), with pronounced performance fluctuations. The addition of AQS alone significantly improved LAS removal to 65 ± 4% without affecting methane production, indicating enhanced LAS transformation via electron shuttling rather than changes in methanogenic activity. Microaeration combined with AQS yielded the best overall performance, increasing LAS removal to 77 ± 1%, COD removal to 92.3 ± 3.8%, total methane production to 5.6 ± 0.7 L/day, and specific methane yield to 0.50 ± 0.11 LCH<sub>4</sub>·gCOD<sub>app</sub><sup>−1</sup>.

Electrokinetic (EK) remediation and hydraulic gradient (HG) treatments were applied to soils with organic matter (OM) contents of 5 %, 30 %, and 50 %. Results showed that PFAS removal was highly influenced by the molecular structure of the species. Both EK and HG were effective at mobilizing short-chain PFAS, which are more mobile in porewater. However, moving longer-chain or more strongly sorbing PFAS was more challenging. These compounds responded better to HG due to the stronger advective forces and may require a combination of HG and EK to achieve significant mobilization. Overall, PFOS, FOSA, and PFDA showed limited mobilization under either treatment due to their stronger sorption to soil organic matter, which restricts both electrokinetic and hydraulic transport.
