“…The choices of raw materials to choose from for the production of activated carbon are so wide and they can be easily obtained from the agriculture or any plant-based sectors. These materials are such as the coconut tree sawdust, silk cotton hull, palm kernel shell, pea shells, 12 peel of cucumis sativa fruit, 13 rice husk, 14 perlite, 15 bagasse°y ash, 3 casuarinas charcoal 16 and teak sawdust. 17 However, di®erent types of adsorbents have di®erent physical properties, although they have similar working principles as well as di®erent selectivity towards di®erent dyes.…”

The study on the removal of methylene blue (MB) and orange-G dyes using magnetic biochar derived from the empty fruit bunch (EFB) was carried out. Process parameters such as pH, adsorbent dosage, agitation speed and contact time were optimized using Design-Expert Software v.6.0.8. The statistical analysis reveals that the optimum conditions for the maximum adsorption of MB are at pH 2 and pH 10, dosage 1.0 g, and agitation speed and contact time of 125 rpm and 120 min respectively. While for orange-G, at pH 2, dosage 1.0 g, and agitation speed and contact time of 125 rpm and 120 min respectively. The maximum adsorption capacity of 31.25 mg/g and 32.36 mg/g for MB and orange-G respectively. The adsorption kinetic for both dyes obeyed pseudo-second order.
