Formaldehyde and BTEX have been used for different industries and other activities. They release many ways that negatively affect the environment and human health due to inadequate ventilation and rapidly increasing oscillation conditions. The widely used technology, which activated carbon, is emerging new studies on air pollutants removal. This study was produced activated carbon for formaldehyde and BTEX removal from Aesculus hippocastanum L. biomass. It was used as organic waste that is abundant in nature. The carbonization was taken place at 600 °C and chemical activation by mixing with ZnCl₂. The produced activated carbon has a surface area is 1858.42 m²/g. The adsorption capacity acquired from experimental data of VOCs were range from 638 to 1114 µg/g for AC-KN, respectively. The removal capacity of produced activated carbon was investigated in a batch reactor. Also, Freundlich and Langmuir’s isotherms were applied in the study. Accordingly, the experimental data were found compatible with both and a hybrid structure that the formaldehyde and BTEX adsorption by AC-KN was better fitted into the Freundlich model. Overall, the study showed that the produced AC-KN from the Aesculus hippocastanum L. biomass has a perfect potential in the removal of the formaldehyde and BTEX from indoor air.

甲醛和 BTEX 已用于不同的行业和其他活动。由于通风不足和快速增加的振荡条件，它们释放出许多对环境和人类健康产生负面影响的方式。广泛使用的技术，即活性炭，正在出现关于空气污染物去除的新研究。本研究生产了用于从七叶树生物质中去除甲醛和 BTEX 的活性炭。它被用作自然界丰富的有机废物。碳化在 600 °C 下进行，并通过与 ZnCl ₂混合进行化学活化。生产的活性炭表面积为1858.42 m ²/G。从 VOC 的实验数据中获得的 AC-KN 吸附容量分别为 638 到 1114 µg/g。在间歇式反应器中研究了生产的活性炭的去除能力。此外，研究中还应用了 Freundlich 和 Langmuir 等温线。因此，发现实验数据与 AC-KN 对甲醛和 BTEX 的吸附更适合 Freundlich 模型的混合结构兼容。总体而言，该研究表明，由七叶树生物质生产的 AC-KN在去除室内空气中的甲醛和 BTEX 方面具有完美的潜力。
