Magnetic and photocatalytic composite particles of m-poly[EGDMA-1-VIM]@WO3 were synthesized via suspension polymerization using Ethyleneglycoldimethacrylate and 1-Vinylimidazole. These particles were designed to remove Reactive Black 5 dye from textile wastewater through adsorption and photocatalytic decolorization. FTIR, XRD, ESR, BET and SEM–EDS elemental mapping analyses were performed to characterize the synthesized polymer composite particles. In adsorption studies, effect of pH, time, adsorbent dosage, temperature and initial dye concentration on capacity were evaluated. Although the increasing the temperature positively influenced the adsorption capacity, a higher amount of polymer had a negative effect. The experimental results aligned well with the Langmuir adsorption isotherm and the pseudo-second-order kinetic model and the thermodynamic parameters were calculated. For the decolorization process of the unadsorbed dye remaining in solution, the effects of time, adsorbent dosage, and dye concentration were investigated, and the decolorization kinetics were elucidated. It was found that under conditions of low dye concentration and high adsorbent dosage, the photocatalytic effect was optimal. Furthermore, the kinetics of decolorization were found to be in accordance with the Langmuir–Hinshelwood model. Highlights A completely new adsorbent, m-poly[EGDMA-1-VIM]@WO3 polymer matrix composite particles with magnetic and photocatalytic properties were synthesised by suspension polymerisation method. FTIR, XRD, ESR, BET and SEM–EDX elemental mapping analyses were carried out to characterise the synthesised m-poly[EGDMA-1-VIM]@WO3 particles. Adsorption processes were carried out. Adsorption isotherms and kinetic parameters were calculated. Photocatalytic decolouration processes were carried out. Decolorization kinetics were elucidated. The photocatalytic decolorization kinetics were consistent with the L–H model. The optimum result was 97.81% removal at 30 mg. L−1 RB5 concentration.
