Effective adsorptive removal of reactive dyes by magnetic chitosan nanoparticles: Kinetic, isothermal studies and response surface methodology.

In the present study, magnetic chitosan (MC) was synthesized, characterized, and used as an efficient adsorbent for the removal of Reactive Red 141 (RR-141) and Reactive Yellow 14 (RY-14) dyes. Synthesized magnetic chitosan nanoparticles were used for characterization with the help of scanning electron microscope (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), and X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The effect of the pH, concentration of pollutants, and adsorbent dosage on the amount of adsorption was studied.
