This work introduces a new sustainable alternative of powdered activated carbon (PAC) - magnetically harvestable and reusable after regeneration via inductive heating - for the adsorptive removal of organic micropollutants (OMP) from secondary wastewater effluents. For this purpose, two commercial PACs - lignite "L" (1187 m/g) and coconut "C"-based (1524 m/g) - were modified with magnetic iron oxide following two different synthesis approaches: infiltration ("infiltr") and surface deposition ("depos") route. The resulting magnetic powdered activated carbons (mPAC) and their precursor PACs were fully characterized before application.

- Spray-drying is a versatile technique for engineers and materials chemists that helps create multifunctional and hybrid materials.
- The process allows for various material formation strategies, including the assembly of nanoparticles, chemical syntheses, and the design of templated materials, all while accommodating fragile components.
- Despite its advantages in creating unique materials with combined properties for applications like catalysis and storage, spray-drying presents several challenges that are discussed in the article.
