Impact of Surface Chemistry on the Removal of Indigo Carmine Dye Using Apricot Stone Active Carbon
A biomass agricultural waste material, i.e. apricot stone, was used as an adsorbent either as received (AP), after carbonization at 500°C (C-AP), and after chemical activation using H 3 PO 4 (H-APC) or using KOH (K-APC) followed by carbonization at 500°C. The four adsorbents were characterized by va...
