Novel Magnetic Silica-Ionic Liquid Nanocomposites for Wastewater Treatment

Magnetic removal of acid dyes from wastewater with ionic liquid linked-nanoparticles

The acid dyes are one of the most widely used commercial dyes used in the textile industries. This work investigates the ability of magnetite nanoparticles functionalized with imidazolium based ionic liquid as an efficient sorbent for removal of the Acid Blue 113 from wastewater. Fourier Transform Infrared Spectroscopy FT-IR, X-ray diffraction XRD and Transmission Electron Microscopy TEM were u...

Novel Poly ( Ionic Liquid )

Ionic liquid biodegradability depends on specific wastewater microbial consortia.

Complete biodegradation of a newly-synthesized chemical in a wastewater treatment plant (WWTP) eliminates the potential for novel environmental pollutants. However, differences within- and between-WWTP microbial communities may alter expectations for biodegradation. WWTP communities can also serve as a source of unique consortia that, when enriched, can metabolize chemicals that tend to resist ...

Adsorption Kinetics at Silica Gel/Ionic Liquid Solution Interface.

A series of imidazolium and pyridinium ionic liquids with different anions (Cl(-), Br(-), BF₄(-), PF₆(-)) has been evaluated for their adsorption activity on silica gel. Quantification of the ionic liquids has been performed by the use of RP-HPLC with organic-aqueous eluents containing an acidic buffer and a chaotropic salt. Pseudo-second order kinetic models were applied to the experimental da...

Magnetic behaviour of novel polymeric nanocomposites

The challenge to synthesize and characterise novel materials exhibiting outstanding properties requires the involvement of interdisciplinary groups with complementary expertise. This is the case of polymeric films and gels with incorporated magnetic components. Particularly, PVC composite matrix where magnetic nanoparticles are embedded represents one of the most attractive and emerging type of...
