The promising characteristics of nanoscale zero-valent iron (nZVI) have not been fully
exploited owing to intrinsic limitations. Carbon-enriched biochar (BC) has been widely used …

Several studies, which have been carried out on water and wastewater treatment with spinel
ferrite nanoparticles (SFNPs) and spinel ferrite nanocomposites (SFNCs) confirmed their …

Spinel ferrite (SF) magnetic materials are an important class of composite metal oxides
containing ferric ions and having the general structural formula M 2+ Fe 2 3+ O 4 (where M …

Ferrimagnetic iron oxide nanoparticles (magnetite or maghemite) have been the subject of
an intense research, not only for fundamental research but also for their potentiality in a …

Many researchers have used nanoparticles as adsorbents to remove water pollutants
including arsenic after modifying the properties of nanoparticles by improving reactivity …

Providing clean and affordable water to meet human needs is a grand challenge of the 21st
century. Worldwide, water supply struggles to keep up with the fast growing demand, which …

There is a need for the development of low-cost adsorbents to removal arsenic (As) from
aqueous solutions. In this work, a magnetic biochar was synthesized by pyrolyzing a mixture …

Global deterioration of water, soil, and atmosphere by the release of toxic chemicals from the
ongoing anthropogenic activities is becoming a serious problem throughout the world. This …

Arsenic (As) is toxic to human and is often found in drinking water in India and Bangladesh,
due to the natural abundance of arsenides ores. Different removal procedures such as …

In nanotechnology, the green synthesis of nanoparticles (NPs) is a new research trend in
science and engineering because it is nontoxic or less hazardous, eco-friendly, efficient, and …
