Microwave functionalization of titanium oxide nanoparticles with chitosan nanolayer for instantaneous microwave sorption of Cu(II) and Cd(II) from water.

The present study is aimed to evaluate the microwave-enforced sorption approach (MES) for instantaneous extraction and removal of trace concentration of metal ions using microwave-synthesized titanium oxide nanoparticles-bonded-chitosan nanolayer (NTiO-NCh). The proposed and designed nanocomposite was characterized by different techniques. The coveted ions were allowed to heat in presence of NTiO-NCh nanocomposite inside a microwave apparatus for 5-20s to execute the sorption process.

Immobilization of chitosan nanolayers on the surface of nano-titanium oxide as a novel nanocomposite for efficient removal of La(III) from water.

A novel nanocomposite has been designed and synthesized via surface crosslinking of chitosan nanolayers (NChit) with titanium oxide nanoparticles (NTiO) using glutaraldehyde (Glu) as the crosslinking agent. A simple and green surface chemical reaction was accomplished by the aid of microwave heating process to enforce surface encapsulation and functionalization for the production of the aimed NTiO-Glu-NChit nanocomposite. The average particles size of nanocomposite was characterized in the range of 52-58nm using SEM and confirmed by the HR-TEM.
