Effect of CO₂ Flow Rate on the Pinang Frond‐Based Activated Carbon for Methylene Blue Removal

Abstract

Activated carbons are regularly used the treatment of dye wastewater. They can be produced from various organics materials having high level of carbon content. In this study, a novel Pinang frond activated carbon (PFAC) was produced at various CO2 flow rates in the range of 150–600 mL/min at activation temperature of 800°C for 3 hours. The optimum PFAC sample is found on CO2 flow rate of 300 mL/min which gives the highest BET surface area and pore volume of 958 m2/g and 0.5469 mL/g, respectively. This sample shows well-developed pore structure with high fixed carbon content of 79.74%. The removal of methylene blue (MB) by 95.8% for initial MB concentration of 50 mg/L and 72.6% for 500 mg/L is achieved via this sample. The PFAC is thus identified to be a suitable adsorbent for removing MB from aqueous solution.

Equilibrium, Kinetics, and Thermodynamics of Remazol Brilliant Blue R Dye Adsorption onto Activated Carbon Prepared from Pinang Frond

“…The sample produced was stored in air-tight container for further characterization and adsorption studies. The detail of preparation was described in the [14].…”

“…The surface area was determined using the Brunauer-Emmet-Teller (BET) equation which is the most usual standard procedure used when characterizing an activated carbon. It was found that the BET surface area, average pore diameter, and pore volume of the PF-AC were 958.23 m 2 /g, 2.32 nm, and 0.5469 cm 3 /g, respectively [14]. to prepare the concentration of 1 g/L dye solution.…”

“…It mainly grows in East Africa, Arabian Peninsula and Asia. However, pinang frond which is part of this plant is considered as waste and usually disposed as solid waste [14]. The use of pinang frond (PF) as feedstock for activated carbon production would turn the pinang frond into value added commodities and this raw material is renewable and potentially less expensive to manufacture.…”

Oxidation of Disperse Carbon Materials

“…Известно [1][2][3], что повышение температуры процесса сопровождается меньшим порообразованием и большим обгаром (окислением по поверхности) материала. Указывается, что на протекание процесса (порообразование или окисление по поверхности) влияет расход окислителя [4] и природа окисляемого материала [5][6][7][8][9]. Отмечается [10], что при использовании воздуха (кислорода) процесс следует проводить при более низких температурах.…”

Effect of Activation Time on the Pinang Frond based Activated Carbon for Remazol Brilliant Blue R Removal

“…Therefore, other alternative precursors which are inexpensive and abundantly available for activated carbon production have been investigated. From the literature, oil palm stone [4], pinang frond [5], banana stalk [6], bamboo species [7], coffee husk [8], date pits [9], oil palm shell [10] and Parkinsoniaaculeatea wood [11] have all been used to prepare activated carbon.…”
