The synthesis of javanese bamboo charcoal for purifiying cooking oil

Abstract

Synthesis of bamboo charcoal from Javanese bamboo has been carried out at a temperature of 400°C with a yield of 30.86%. The syintesis of javanes bamboo charcoal by heating proses with activated using NaCl. Activated bamboo charcoal was characterized using reference to SNI 06-3730-1995 regarding technical activated charcoal including water content, volatile content, total ash content, carbon content, iodine absorption and absorption of methylene blue. Activated bamboo charcoal also characterized its functional groups using FTIR and morphology using SEM. The activated bamboo charcoal which has the characteristics of a water content of 4.36% (w/w), an ash content of 1.28%(w/w), a vapor content of 5.28%(w/w), a carbon content of 80.08% (w/w), an iodine absorption capacity of 1146.35 mg/g and the absorption capacity of Methylene blue 421.46 mg/g which according to SNI 06-3730-95 standards concerning activated charcoal. From the FTIR result activated bamboo charcoal shows an absorption at (1500-1600) cm−1, indicating the presence of a C=O bond, the hydroxyl group which is bound O-H (3400-3500) cm−1 and CO (1300-1400) cm−1 which is capable of absorb color and free fatty acids. The morphological characteristics of activated bamboo charcoal are more porous than non-activated bamboo charcoal, thereby increasing its surface area and adsorption ability. The ability of activated bamboo charcoal in processing used cooking oil is able to reduce turbidity, color and odor, water content, acid number and peroxide number of cooking oil after the adsorption process. The result showed that the water content is 0,08% (w/w), peroxide number 5.45 mek O2/Kg, FFA 0.24 mg KOH/g which fulfills SNI 3741: 2013 Standard.

Application of Activated Carbon from Cocoa Pod Husk (Theobroma cacao L.) in Used Cooking Oil

“…The purification of used cooking oil aims to separate the products of degradation reactions, such as water, peroxides, free fatty acids, aldehydes, and ketones, from the oil. One way to improve the quality of used cooking oil is adsorption using activated carbon [4,5].…”

Characterization of Indonesian Bamboo Charcoal for Enhanced Adsorption Capabilities

“…Due to its numerous potential applications, activated charcoal has become a common part of our daily lives. It is known for its ability to adsorb heavy metal ions and remove dye waste (Yuvaraj, 2021), purify water (Chien and Fujimoto, 2017), clean used cooking oil (Suryandari and Kusuma, 2021), and cater to our daily needs such as facial wash and toothpaste (Rattanawut, 2018;Megalobrama et al, 2021). Along with industrial development, the need for activated charcoal is also increasing, both for export and domestic.…”

“…In 2001, the production of activated carbon reached 30,161 tons per year, while the export volume amounted to 11,834 tons. Large countries such as the United States have a per capita demand of 0.4 kg per year, while in Japan, it ranges from 0.2 kg per year (Suryandari and Kusuma, 2021) Activated charcoal can be obtained from various sources, for example from coconut shells (Akinlabi et al, 2017), coconut husk, coal (Kumar et al, 2021), bamboo (Chien and Fujimoto, 2017;Lin and Lin, 2018), rice husks (Van, Thuy and Thi, 2014), plant seeds (Ogungbenro et al, 2017) and others. Recently, activated charcoal in general is used around 300.000 tons/year.…”
