Photopolymerization of Coating Materials for Protection against Carbon Steel Corrosion.

This work demonstrated a workable approach for the synthesis of a re-healing polyaniline-modified epoxy resin coating material via photopolymerization. The prepared coating material exhibited low water absorption, allowing it to be used as an anti-corrosion protective layer for carbon steel. First, graphene oxide (GO) was synthesized through the modified Hummers' method.

Design an Epoxy Coating with TiO/GO/PANI Nanocomposites for Enhancing Corrosion Resistance of Q235 Carbon Steel.

In this work, a ternary TiO/Graphene oxide/Polyaniline (TiO/GO/PANI) nanocomposite was synthesized by in situ oxidation and use as a filler on epoxy resin (TiO/GO/PANI/EP), a bifunctional in situ protective coating has been developed and reinforced the Q235 carbon steel protection against corrosion. The structure and optical properties of the obtained composites are characterized by XRD, FTIR, and UV-vis. Compared to bare TiO and bare Q235, the TiO/GO/PANI/EP coating exhibited prominent photoelectrochemical properties, such as the photocurrent density increased 0.

Groundwater arsenic removal using granular TiO2: integrated laboratory and field study.

High concentrations of arsenic (As) in groundwater pose a great threat to human health. The motivation of this study was to provide a practical solution for As-safe water in As geogenic areas using granular TiO2 (GTiO2). The kinetics results indicated that the As (III/V) adsorption on GTiO2 conformed to the Weber-Morris (WM) intraparticle diffusion model.

Evaluation of chromium bioaccessibility in chromite ore processing residue using in vitro gastrointestinal method.

Incidental ingestion of Chromite ore processing residue (COPR) particles poses a potential health risk. The purpose of this study was to determine the Cr bioaccessibility from COPR using the in vitro gastrointestinal (IVG) procedure. The bioaccessible Cr(VI) was 53.
