Oxidised biochar from palm kernel shell for eco-friendly pollution management / Sylbialin Amin, Robert Thomas Bachmann and Soon Kong Yong

Oil palm plantations produce palm kernel shell (PKS) that can be converted into biochar for environment-friendly soil remediation and water treatment. Oxidation with hydrogen peroxide (H2O2) may enhance surface characteristics and the quality of low-rank PKS biochar as a sorbent for environmental de...
