Increased levels of heavy metals (HMs) in aquatic environments poses serious health and
ecological concerns. Hence, several approaches have been proposed to eliminate/reduce …

Heavy metals (HMs) are among the most hazardous water pollutants due to their toxic (when
ionized in water) and non-biodegradable nature. Although there are several methods that …

The use of biomass and waste to produce adsorbent reduces the cost of water treatment.
The bio-char of Sargassum oligocystum (BCSO) was modified with MnFe 2 O 4 magnetic …

Abundant quantities of orange waste are produced annually, and their use for sewage
treatment is admirable. The orange seeds powder was modified with Fe3O4 and applied for …

Herein, an environmentally friendly and efficient adsorbent of microalgae (MAG) was
applied for the removal of crystal violet (CV) and methylene blue (MB) dyes from aqueous …

Using biomass-based catalysts in biodiesel production can make the process more
economical and environmentally friendly. In this study, a new magnetic nanocatalyst was …

The elimination of heavy metal ion contaminants from residual waters is critical to protect
humans and the environment. The natural clay (dolomite and quartz) based composite Fe 3 …

In this work, we choose a simple, green hydrothermal method for the fabrication of a pure
phase of CuMn 2 O 4 nanostructures in the presence of onion as a cap** agent, for the …

In the present study, to remove heavy metal ions Cd 2+ and Pb 2+ from aqueous solution
and industrial effluent, a new magnetic nanocomposite based on eggshell/starch/Fe 3 O 4 …

Water contamination due to the artificial dyes from domestic and industrial wastewater is one
of the most crucial environmental issues and problems that the use of an effective adsorbent …
