The potential use of PEI modified biochar for different environmental applications

Man-made pollution is hazardous to both the environment and human health. This study attempts to develop a low-cost, biobased adsorbent for CO2 capture and heavy metal removal. The adsorption behavior of CO2 from air and Pb (II) from aqueous sy...
