CeO2–SiO2 nanoadsorbents synthesized via a simple and energy-efficient approach were used for the removal of ionic dyes from single and binary aqueous solutions. The effects of pH, temperature, contact time, and adsorbate/adsorbent dosage on adsorption performance were examined as a function of the CeO2–SiO2 ratio. Adsorption isotherms, kinetics, and thermodynamic parameters were interpreted using characterization data and theoretical models. The adsorbent with the highest CeO2 content exhibited the best adsorption performance, following pseudo-second-order kinetics and showing strong pH dependence. High selectivity (>97%) was obtained. Moreover, effective desorption and good reusability were observed, with only a slight decline in adsorption efficiency after 10 cycles. Continuous adsorption experiments conducted in a packed column revealed good agreement with the Thomas model, yielding breakthrough capacities of 86.22 and 78.18 mg g−1 for RR120 and MB, respectively.
