  • The permissible limit of Arsenic set by WHO is 10µg/L
  • The main source of As in the water is geogenic and some anthropogenic activities.
  • Biochar is one of the best adsorbents that potentially remove As from contaminated water.
  • Modified biochar is more effective in removing Arsenic from the water.
  • Modified biochar having many oxygenated functional groups are available.


In many nations throughout the world, groundwater is regarded as the main source of drinking water.  Clean and safe groundwater is a top concern for water authorities everywhere in order to preserve the sustainability of resources. Groundwater resources are vulnerable to a variety of contamination, with arsenic (As) being a major pollutant in some places as a result of natural or anthropogenic activities. Because of the technical complexity and high expense of conventional As removal treatment systems, it is the goal of many researchers to create methods of groundwater treatment that are successful, environmentally benign and economical. The technical summary is meant to complement the understanding of researchers, scholars, and scientists. Emphasizing the function of biochar as a sorbent and imagining the potential modification to it as decontamination methods, biochar production, characterization and adsorption mechanism of arsenic onto the surface of the biochar/modified biochar.

Keywords: Biochar; arsenic; adsorption; mechanism; modified biochar.
