Correlation and the Impact of Feedstock Type and Production Conditions on Heavy Metal Adsorption by Biochar: A Comprehensive Meta-Analysis

Abstract

Biochar (BC) is a ubiquitous, porous, carbonaceous solid produced by the pyrolysis of biomass under anaerobic conditions, which can be used as a fuel as well as an adsorbent. Although the potential use of biochar in aqueous systems to adsorb heavy metals has gained attention recently,
