Abstract

Areca catechu L., commonly known as areca nut, is a tropical plant with many benefits, yet its fruit peel remains underutilized. In fact, the peel contains a high cellulose content (57.35%), making it a promising precursor for producing carbon-based materials such as biochar and hydrochar. These materials can be used as adsorbents for wastewater treatment, particularly for the removal of synthetic dyes like Congo red. Biochar is produced via pyrolysis, while hydrochar is synthesized through the hydrothermal carbonization (HTC) process. However, both materials still face limitations in terms of particle size and surface area, which can hinder their adsorption efficiency. To overcome these limitations, structural modification using the High-Energy Milling (HEM) method was applied to produce nano-sized materials: nano-biochar (Nano-BC) and nano-hydrochar (Nano-HC) derived from areca nut peel. The synthesized materials were characterized using XRD, FTIR, SEM, and BET analyses. Results showed a significant increase in surface area after HEM treatment. The BET surface areas for BC, Nano-BC, HC, and Nano-HC were found to be 22.38 m²/g, 49.34 m²/g, 41.93 m²/g, and 77.62 m²/g, respectively, indicating the effectiveness of the nanostructuring process. Adsorption tests on Congo Red dye showed that Nano-HC exhibited the highest maximum adsorption capacity at 593.410 mg/g, followed by HC at 171.869 mg/g, Nano-BC at 199.297 mg/g, BC at 107.623 mg/g, and raw areca nut peel at 74.857 mg/g. The adsorption process followed the pseudo-second-order kinetic model, indicating that chemisorption was the dominant mechanism. Regeneration tests revealed that although Nano-BC and Nano-HC had high initial adsorption capacities, they experienced significant efficiency declines after three cycles, dropping to 19.83% and 16.34%, respectively. In contrast, Biochar and Hydrochar showed more stable regeneration performance, maintaining efficiencies of 27.55% and 48.14% at the third cycle. These findings suggest that while nano-modified materials offer high initial adsorption performance, the more stable structure of Biochar and Hydrochar allows for more consistent reuse. Overall, the results confirm that areca nut peel-based adsorbents, particularly in nano-modified forms, hold strong potential for sustainable applications in colored wastewater treatment.
