An effective porous biochar adsorbent derived from Platanus orientalis leaves for the removal of rhodamine B: adsorption performance and mechanism insight.
In this study, a series of porous biochar material (PoLC-600, PoLC-700, PoLC-800) adsorbents were fabricated from waste Platanus orientalis leaves via pre-carbonization combined with KOH activation. The optimized PoLC-800 exhibited a large specific surface area of 1384 m2 g-1 and displayed an ultrahigh maximum adsorpti...
