📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではバイオマス廃棄物の有効活用がGX政策の一部として注目されており、廃棄物由来の吸着材は排水処理や土壌浄化の分野で応用可能性がある。ただし、直接的な脱炭素や開示制度との関連は薄い。
In the global GX context
Globally, this research aligns with circular economy principles and waste valorization, which are part of broader sustainability efforts. However, it does not directly address climate disclosure or transition finance, limiting its direct GX relevance.

📄 Abstract（原文）
This research explores the production of activated carbon from a lignocellulosic precursor, corn cobs, as a potential method for the removal and adsorption of phenolic and nitrophenolic compounds. Colombia is a major corn producer, with a national production of 1,559,194 tons in 2024. Currently, approximately 0.5 to 3.2 kg of corn residue per kg of product is not commercially utilized. The objective is to focus on the removal of phenol, 2-nitrophenol, 4-nitrophenol, and 2,4-dinitrophenol from simulated solutions to evaluate the adsorption capacity under optimal conditions. Phenolic and nitrophenolic compounds are considered highly toxic molecules for the environment, especially in the plastics and agrochemical production sectors. These compounds are pollutants in wastewater due to their impact on aquatic life and human health. This not only contributes to the utilization of residual biomass but also to the circular economy by promoting its valorization in environmental remediation processes. The diameter and average volume of the pores are large enough to promote rapid diffusion kinetics of the phenolic compounds within the pore structure, which varies from 0.207 to 0.544 cm3 g−1, and their adsorption capacity. The most adsorbed phenol was found to be 4-nitrophenol, with up to 97 mg of contaminant (4-nitrophenol) adsorbed per gram of activated carbon (sample designated AC-TK), at initial concentrations ranging from 0.0 ppm to 3.0 ppm. Furthermore, magnetite plays a crucial role in the adsorption of 2-nitrophenol. With this compound, up to 86 mg of 2-nitrophenol per gram of activated carbon was adsorbed at a concentration of 14 ppm, whereas without magnetite, a smaller amount was adsorbed at lower initial concentrations (ppm) for the same compound.
