This paper reports a novel, low-cost and facile approach to prepare a hybrid material consisting of zeolite, Fe₃O₄ and graphitic carbon nitride as a sorbent to remove methyl violet 6b (MV) from aqueous solutions. To improve the performance of the zeolite for the removal of MV, graphitic carbon nitride (with different C-N bonds and conjugated π region) was used. Also, to perform an easy and fast separation of sorbent from aqueous media, magnetic nanoparticles were incorporated into the sorbent. The prepared sorbent was characterized by different analytical techniques such as X-ray diffraction analysis, Fourier transform infrared, field emission scanning electron microscopy and energy-dispersive X-ray analysis. The effects of four parameters of initial pH, initial concentration of MV, contact time and the adsorbent amount on the removal process were investigated and optimized by the central composite design method. The removal efficiency of MV was modeled as a function of the experimental parameters an optimal removal efficiency of 89% and maximum adsorption capacity of 384.61 mg g^{− 1} was achieved using 10 mg of the sorbent at a 2-min contact time. The applied composite can efficiently remove MV from various wastewater samples (paint, textile industries, pesticide production wastewater samples and municipal wastewater).
