Porous hybrid composite for removal of metal ions waste

What is it about?

In our study, Cd (II), Pb (II) and Al (III) metal ions removal was evaluated, using a chitosan‐TiO2‐polyurethane based composite. Composite synthesis variations in composition and temperature were studied; morphology characterization was conducted by SEM, EDS‐STEM and X‐ray micro‐CT. Wastewater samples in different pH solutions, and in static and dynamic systems were analyzed by ICP‐MS. Also, the photo‐degradation of azo dyes in these systems was studied by UV–vis spectrophotometry. A dynamic removal system was built as possible water treatment plant prototype.

Why is it important?

For almost three decades, heavy metal pollution has been studied and several treatment techniques have been proposed. Nevertheless, this contamination in wastewater is still a severe problem.
