TLDR Activated carbon fibers from Metaplexis japonica seed hair are highly effective for removing the dye methylene blue from water.
In a study published on June 1, 2020, researchers developed activated carbon fibers (ACFs) from the seed hair fibers of Metaplexis japonica (MACFs) as an efficient adsorbent for methylene blue (MB), a harmful dye in wastewater. The MACFs, prepared through alkali treatment, phosphoric acid activation, preoxidation, and carbonization, showed a high specific surface area of 1882.003 m²/g and a total pore volume of 1.613 cm³/g. They demonstrated a maximum adsorption capacity of 943.372 mg/g for MB at 25°C, with the adsorption process fitting the Langmuir model, indicating monolayer adsorption. The MACFs achieved a 100% dye removal rate in one-time filtration and were recyclable. The study concluded that the hollow structure, low density, and effective activation process of the MACFs contributed to their high adsorption efficiency, offering a promising solution for water treatment and sustainable waste management. The research was supported by various projects and foundations, and no competing financial interests or personal relationships were disclosed.
