Engineered nano-zirconium oxide-crosslinked-nanolayer of carboxymethyl cellulose for speciation and adsorptive removal of Cr(III) and Cr(VI)

A novel nanosorbent is designed via crosslinking of nanolayer carboxymethyl cellulose (CMC) onto the surface of nano‑zirconium oxide (Nano-ZrO2) using glutaraldehyde for the formation of Nano-ZrO2-glu-CMC. The nanosorbents were characterized using TGA, SEM, HR-TEM, FT-IR and surface area analysis. The particle size of Nano-ZrO2-glu-CMC was 22–39 nm. The potential implementation of Nano-ZrO2-glu-CMC sorbent for selective speciation and extraction...
