Manufacture of Low-cost Activated Carbon Using Sago Palm Bark and Date Pits by Physiochemical Activation

Abstract

Two raw materials, sago palm bark (SPB) and date pits, were utilized as precursors to prepare high porosity activated carbon (AC). The porosity of these two raw materials was compared with that of commercial AC made from coconut shells. The physicochemical activation method was used for AC preparation, and it consisted of two steps, carbonization and activation. The activation process was performed using zinc chloride (ZnCl2) as an activation agent. N2 adsorption-desorption analysis was carried out to characterize the porosity of AC. Thermogravimetric analysis (TGA) was conducted for the two raw materials. The adsorbent made from SPB, which showed the maximum surface area of 1634 m 2 /g at the 700 °C activation temperature for one hour, while the surface area of prepared AC from date pits was 1367 m 2 /g. Both prepared ACs had a larger surface area than commercial AC made with coconut shell (1348 m 2 /g).

Synthesis and characterization of activated carbon derived fromTectona grandissawdust via green route

“…However, for this purpose, other chemical compounds have been also used (e.g., NaOH and H 3 PO 4 or ZnCl 2 ). Further, most of these have environmental and economic issues due to their elevated corrosiveness and toxicity 2,9 . So, it becomes important to develop an alternative method for the synthesis of activated carbon.…”

Removal of Methylene Blue Dye from Synthetic Wastewater using Kenaf Core and Activated Carbon

“…The agriculture materials consider a favorer option in the search about feasible rout in adsorption process. Nowadays, many different types of agricultural materials used to prepare activated carbon such as sago palm park [7], date pits [8], and industrial waste products (metal hydroxide sludge, carbon waste slurries, and coffee wastes) [9]. In this study, Kenaf core was examined for its ability to remove textile-based cationic methylene blue (MB) dye from synthetic wastewater and compared to the well-known adsorbent, the activated carbon.…”

Performane of Activated Carbon Adsorption in Removing of Organic Pollutants from River Water

“…due to its high degree of micro porosity, just one gram of activated carbon has a surface area in access of 500 m 2 , with 1500 m 2 being readily achievable as determined by adsorption of nitrogen gas [3]. Many previous studies investigated the using of different agricultural waste as a raw material to produce activated carbon, such as rice husk [4], jute and coconut fibre [5], coconut husk [6], sago palm bark [7], and modified activated carbon [8,9,10]. The activated carbon contractors generally consist of the activated carbon that will act as the filter bed inserted in the contractor, commonly fabricated from concrete or steel columns in rectangu-lar or cylindrical shape.…”
