Chemically Modified Coconut Shell Biochar for Removal of Heavy Metals from Aqueous Solution

In this study, coconut shells were converted into biochar via pyrolysis and chemically modified via an acid-base treatment to enrich its adsorption capabilities. Batch experiments were carried out to analyze the adsorption potential of the modified coconut shell (MCSC) for removal of chromium, nicke...
