Magnetic γ-Fe2O3 based nanomaterials: synthesis, characteristics, and application in pollutant adsorption: Empirical modeling and process optimization by response surface methodology (RSM) and artificial neuralnetwork (ANN) simulation

Water pollutants like dyes. Enter to the various ecosystem and media annually by textile,paper, cosmetics, pharmaceutical, leather and food activities.[1] Therefore, dyes removalspecially in mixture system is challenging that must be cope with to produce safe and cleanenvironment.[2] presence of latge number of dyes with similar charge generate greatproblems one of most and great requirment in complicated dyes solution is their accurate andrepetable evaluation and monitoring. This point is limited by severe and serious peaksoverlapping.
