they have been entered to water bodies, air and soil and have become one of the major …

This review presents a holistic analysis of the synthesis and efficacy of nanosorbents
towards the waste water purification by the removal of selected heavy metal ions, with …

Biochar is a carbonaceous material produced by thermal treatment, eg, pyrolysis, of biomass
in oxygen-deficient or oxygen-free environment. Nitrogen containing functional groups of …

Adsorption using different adsorbents is seen as the most effective method of treating
wastewater contaminated by heavy metal ions such as copper ions. In particular, nano …

Significant aspects of the world's water scenario, primarily associated with global population
growth and climate change, necessitate new technology implementation to ensure a supply …

In this work, magnetite nanoparticles, synthesized by the sol-gel citrate-nitrate method, were
applied as precursors for methylene blue degradation in a simulated aqueous solution. The …

At high environmental concentration, some heavy metals display adverse health effects on
living organisms and ecosystems. They bioaccumulate in the food chain and end up in …

Although heavy metals are typically found in trace levels in natural waterways, most of them
are hazardous to human health and the environment, even at extremely low concentrations …

The discharge of toxic heavy metals including zinc (Zn), nickel (Ni), lead (Pb), copper (Cu),
chromium (Cr), and cadmium (Cd) in water above the permissible limits causes high threat …

In this research, natural asphalt as a mineral carbonuous material was converted to sodium
