Arsenic mitigation approach in soil by some indigenous sources of biochar of different pyrolysis temperature
Water-soluble inorganic pollutants may constitute an environmental toxicity problem if their movement through soils and potential transfer to plants or groundwater is not arrested. Biochar has recently been used to sequester carbon and remediate soil with both heavy metal and organic pollutants. The characteristics of biochar are influenced mainly by the preparation temperature and biomass sources. Biochars were produced from three different sources (viz., cow dung, poultry manure, and sewage sludge) at two different temperatures (low temperature - +250ºC and high temperature - +450º C).
