The application of biochar derived from various biomass to treat heavy metal pollution has received particular attention in recent years. Lignin is an abundant, highly aromatic byproduct from the paper-making industry with a low utilization rate, which is a potential feedstock for biochar preparation. In this study, lignin was carbonized at different temperatures by microwave heating to obtain biochars (LBx), and the effect of pyrolysis temperature on biochar properties, Cd(II) adsorption behavior, and mechanisms was comprehensively investigate...
