Dye Extraction by Functionalized Magnetic Nanoparticles with Surfactants and Cyclodextrins through Specific and Host-Guest Interactions.

ABSTRACT: Functionalized magnetic nanoparticles (NPs) were synthesized by using different surfactants and cyclodextrins (CDs) for the extraction of toxic dyes from the aqueous bulk at room temperature to exploit the surfactant/CD-dye interactions operating at the solid-liquid interface. The extraction of dyes was monitored by UV-visible studies and quantitatively estimated. Both hexamethylene bis(hexadecyl dimethylammonium bromide) (16-6-16) and tris(2-(N-dodecyl N,N-dimethylammonio)ethylamine) tribromide (TriCAT) functionalized magnetic NPs proved to be excellent extractors, whereas extraction was highly facilitated at high or low pH when CD-functionalized magnetic NPs were used. Self-association among the dye molecules impeded the extraction. A combination of both polar as well as no
