A degradation efficiency of ~82% was achieved within 90 min, with apparent pseudofirst-order kinetics (<i>k</i> ≈0.017 min<sup>−1</sup>). However, the observed kinetics are governed by a quasisteady-state flux of reactive species rather than intrinsic reaction rates. OES analysis confirms the generation of key reactive oxygen and nitrogen species (RONS), including •OH, O<sub>3</sub>, and H<sub>2</sub>O<sub>2</sub>, whose formation is directly linked to electron temperature (~12 eV) and discharge characteristics. A two-stage degradation mechanism is identified: an initial reduction-dominated phase associated with chromophore cleavage, followed by an oxidation-dominated phase driven by RONS leading to fragmentation and mineralization. Physicochemical parameters (pH, EC, ORP, and TDS) reveal strong redox transitions and ionic product formation, supporting the proposed mechanism.

The Cattaneo–Christov flux model is used in place of Fourier's and Fick's laws to incorporate relaxation effects, ensuring a more realistic depiction of energy and solute transport. The energy equation is further refined by incorporating solar radiation and Joule heating, both of which significantly influence thermal behavior under electromagnetic conditions.

Results reveal that the magnetic field and velocity slip tend to suppress fluid motion, leading to higher skin friction, while porous permeability enhances flow and reduces drag. The thermophoretic and Brownian diffusion effects intensify temperature and improve heat transport within hybrid nanofluid due to enhanced particle motion. Moreover, radiation, magnetic field, and Eckert number elevate fluid temperature, indicating stronger energy dissipation and improved thermal efficiency. Conversely, thermal relaxation and temperature slip moderate temperature gradients, enhancing convective heat control.
