The widespread use of perfluoro/polyfluoroalkyl compounds (PFACs) makes it inevitable for them to be released into and affect the environment, and the octanol-water partition coefficient (logK) is a key indicator for evaluating the environmental behavior of trace pollutants and their impact on the environment. However, the determination of logK using experimental means is often time-consuming and laborious, or even unattainable. Therefore, the logKow of 20 per/polyfluoroalkyl compounds obtained from the PubChem database was selected as the object of study, and the 41 chemical descriptors required for modeling were obtained by density-functional theory calculations, and it was found that only two molecular descriptors (A, V) were significantly correlated with the logK, with the correlation of the descriptor A being the was the strongest.

- Microplastics, particularly polystyrene (PS), are a growing pollutant in aquatic environments, creating a need for effective removal methods.
- The study investigates an optimized electrocatalytic oxidation (ECO) technology using a specially designed anode made from Ti/La-Sb-SnO, enhanced with cobalt (Co) as an intermediate layer for better performance and longevity in degrading PS microplastics.
- Results indicate that Co significantly improves the lifespan of the electrode and maintains degradation efficiency at a heat treatment temperature of 400 °C, achieving a PS removal rate of 28.0%, while also generating various degradation products through oxidation.
