Abstract

Synthesis of activated carbon from cempedak peel waste is carried out to utilize biomass waste. This study aimed to synthesize and characterize activated carbon from cempedak peel waste. The synthesis was carried out by chemical activation using phosphoric acid with a dry impregnation ratio of 1:4 (g sample:g H3PO4). Samples impregnated for 24 hours were then heated at 250℃—and then calcined at 350℃ and 450℃. The XRD and FTIR characterization results indicated that the activated carbon obtained had an amorphous structure and the activated carbon obtained had hydroxyl, carbonyl, and carboxylic groups. Activated carbon with the highest yield was obtained at a temperature of 350, namely 43%. The results of determining the water content of activated carbon obtained are 8.36% at 350 0C and 7.1% at 450 ℃. The value of water content and ash content of activated carbon from the skin of this cempedak fruit has met the Indonesian National Standard (SNI 06-3730-1995). The best-activated carbon yield was at a calcination temperature of 450, with the percentage of adsorption efficiency on methylene blue of 98.88%.

Abstract

ABSTRACT Research on the characterisation of activated carbon of white snapper (Lates calcarifer) scales waste, obtained through carbonisation process, fish scales were put in a furnace at 350 oC for 2 hours. Then cooled and sieved with a 100 mesh sieve, characterised by XRD, resulting in three peaks with the strongest intensity at 2θ regions of 26.45o, 32.69o, and 33.60o respectively. The surface acidity of carbon solids before and after activation were (4.48x10-3 and 7.77x10-3) mol/g, respectively. The activation process of white snapper scales (Lates calcarifer), increases the surface area of carbon can react with other chemicals. Subsequently, it was calcined at 450 oC under vacuum conditions for 2 hours with N2 gas, and characterised by XRD. The results showed a shift in 2θ peaks of 26.52o, 29.66o, and 32.77o, respectively. The carbon was activated by soaking with 3 M KOH activator for 15 hours, washed with distilled water, and dried in an oven at 110°C for 1 hour, characterised by XRD, and the peaks with the strongest intensity were obtained at 26.22°C, 29.12°C, and 32.43°C, with increasing basal spacing. Keywords: activated carbon, white snapper scales, XRD
