The removal of textile toxic contaminants is an essential process to provide clean water to the increasing population rate. It requires a design of a selective material to adsorb dyes pollutants with stability, effectiveness and reusability. Regeneration efficiency and recovery extent (RCE) are one of the critical factors to measure the performance of the adsorption process. In this study, magnetic Core-shell beads based on porous carbon@Fe 3 O 4 NPs with high specific surface area were successfully synthesized by simple Co-precipitation method. The structural, textural, chemical and morphological proprieties of the prepared materials were studied by XRD, FTIR, Raman spectroscopy, nitrogen adsorption-desorption, XPS, SEM and TEM. The adsorption kinetic and isotherm data were well fitted to the pseudo-second-order and Langmuir models. Magnetic particles exhibited an excellent ability to adsorb methylene blue (MB) from aqueous solutions with maximum MB adsorption capacity of 180.42 mg/g (porous carbon@Fe 3 O 4 -NPs powder) and 49.66 mg/g (magnetic Core-shell beads based on porous carbon@Fe 3 O 4 -NPs). The synthesized core shell adsorbent showed good magnetic response, high regeneration efficiency with excellent recovery extent. We believe that in the near future these new magnetic Core-shell beads based on porous carbon@Fe3O4-NPs can be used as an alternative to solve the separation problem involving the material pollutant interfaces and can be commercialized as a benchmark adsorbent for the removal of toxic dyes.
