Role of Plant-Based Biochar in Pollutant Removal: An Overview

Abstract

Biochar is a porous material that is produced by pyrolysis, that is, thermal heating under oxygen limited conditions. The potential of biochar has been investigated in various fields like wastewater treatment, soil treatment/improvement, organic/ inorganic pollutant (like metals, dyes, fluoride, phenol, dyes and pesticide etc.). The cost of preparation of biochar is high, so, the researchers have drawn their attention toward the preparation of low cost plant derived biochar. Biochar as adsorbent for pollutant removal have been proved in various studied due to high carbon content, low ash content, large surface area, and high porosity. The present review explores the biochar application in various pollutants removal from aqueous solutions and soil treatments. © 2017 Scrivener Publishing LLC. All Rights Reserved.
