Two decades ago, iron nanoparticles have been widely studied in environmental protection
due to their particular characters. Compared with traditional absorbents, iron nanoparticles …

Hexavalent chromium is mobile, highly toxic and considered as a priority environmental
pollutant. Chromate reductases, found in chromium resistant bacteria are known to catalyse …

We report a one-step fabrication of macroscopic multifunctional graphene-based hydrogels
with robust interconnected networks under the synergistic effects of the reduction of …

Nanoscience emerged in the late 1980s and is developed and applied in China since the
middle of the 1990s. Although nanotechnologies have been less developed in agronomy …

The recent spark in the interest for the usage of nano zero valent iron (nZVI) as a
remediation tool for contaminated land and groundwater is mainly due to its higher reactivity …

In this study, we developed a novel nanocomposite, polyurethane foam impregnated with
zero-valent iron nanoparticles (PU@ nZVI), for the effective removal of chromium (VI) from …

The release of industrial effluents contributes to environmental degradation, posing a
significant challenge to sustainable development. Metol (MTL) is a popular color-develo** …

Nanoscale iron particles have attracted substantial interest due to their unique physical and
chemical properties. Over the years, various physical and chemical methods have been …

The exploitation of different plant materials for the biosynthesis of nanoparticles is
considered a green technology because it does not involve any harmful chemicals. In this …

A combined two-step EC–EF process was designed to simultaneously remove Cr (VI) and
fluoride from pretreated acidic semiconductor effluents. The EC step comprises integrated …
