Abstract The azo dyes Reactive Orange‐16 and Reactive Green‐19 were removed using Aliquat‐336‐incorporated Amberlite XAD7HP resin in batch and in a continuous stirrer vessel. The prepared resin was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, Brunauer‐Emmett‐Teller method, and X‐ray photoelectron spectroscopy. The effect of dosage, initial dye concentration, time, pH, and temperature on the removal efficiency of both dyes was evaluated. Equilibrium, kinetic, and diffusion models were fitted to the batch data. Design calculations for single‐stage batch adsorption were done to scale up the process industrially. The resin was regenerated using ethanol. To intensify the process further, continuous studies were performed in a recirculating stirred vessel at different flow rates and stirring speeds.
