Abstract
The results showed that H3PO4 seems to induce the deepest impact on the P. oceanica fibres by providing the lowest conversion yield (16.9%). Besides, the pore analysis showed that two types of porosity were developed: (i) CACs characterized by an inner structure combining significant fraction of both mesopores and micropores (i.e. CAC-H3PO4, CAC-KOH and CAC-ZnCl2) and (ii) CAC-H2O2 with a large mesoporous structure and a small fraction of microporosity. Dealing with the RAMAN and XPS analysis, it was showed that the main carbon fraction is structurally organized (i.e. graphite), especially for the CAC-ZnCl2 sample. As for the isotherm and kinetic investigation, the experimental and modelling results revealed that CAC-H3PO4 was the best performing activated carbon by removing the highest methylene blue dye amount (137Â mg/g) in the shortest time (1.3Â h to reach the half reaction point).
