Trimethyl Chitosan/Siloxane-Hybrid Coated Fe₃O₄ Nanoparticles for the Uptake of Sulfamethoxazole from Water.

ABSTRACT: The presence of several organic contaminants in the environment and aquatic compartments has been a matter of great concern in the recent years. To tackle this problem, new sustainable and cost-effective technologies are needed. Herein we describe magnetic biosorbents prepared from trimethyl chitosan (TMC), which is a quaternary chitosan scarcely studied for environmental applications. Core@shell particles comprising a core of magnetite (Fe₃O₄) coated with TMC/siloxane hybrid shells (Fe₃O₄@SiO₂/SiTMC) were successfully prepared using a simple one-step coating procedure. Adsorption tests were conducted to investigate the potential of the coated particles for the magnetically assisted removal of the antibiotic sulfamethoxazole (SMX) from
