Summary

This is a companion dataset to an electrochemical microplastic treatment study comparing a boron-doped diamond anode with a photoactive tin-oxide ceramic anode for degrading polystyrene microplastics. The data covers removal efficiency, organic carbon mineralization, and energy use under different current levels and lighting conditions. It supports research into scalable water treatment technologies for microplastic removal.

Polymers

This dataset contains experimental data obtained during the electrochemical and photoelectrochemical degradation of polystyrene (PS) microplastics in aqueous media. Experiments were performed at room temperature using two anode materials: a commercial boron‑doped diamond (BDD) anode and a Sb‑doped SnO₂ ceramic anode coated with a photoactive cadmium ferrite (CdFe₂O₄) layer. The dataset includes the temporal evolution of PS removal efficiency, total organic carbon (TOC) mineralization, kinetic model fitting parameters, raman spectroscopic analysis and specific energy consumption under different applied current intensities (50, 100, and 200 mA) and illumination conditions (dark and visible light).
