摘要

在本研究中，生物炭是从农业副产品椰子椰壳（BC1）和稻壳（BC2）中提取的，用25%的NaOH活化。通过SEM图像、XRD、FTIR和拉曼光谱等分析方法对该材料进行了表征。分析结果表明，碳结构碳是无定形的，具有许多石墨烯层。364.22检测到高比表面积 m2.g-1用于BC1和329.71 当通过N2和CO2吸附进行分析时，具有许多中孔和微孔的BC2的m2.g-1。该材料还显示出对纺织废水的阴离子和阳离子染料吸附能力，遵循Langmuir和Freundlich模型，其中BC2比BC1具有更好的最大吸附能力，6.519 MO和8.612的mg.g-1 mg.g-1表示MB。

Preparation and Characterization of Biochar Derived from Agricultural By-Products for Dye Removal

In this study, biochar was derived from the agricultural by-products coconut coir (BC1) and rice husk (BC2) activated with NaOH 25%. This material was characterized through analytical methods such as SEM images, XRD, FTIR, and Raman. Analysis results indicated that the carbon structure carbon is amorphous and with many graphene layers. A high specific surface area was detected with 364.22 m2.g-1 for BC1 and 329.71 m2.g-1 for BC2 with many meso and micropores when analyzed by N2 and CO2 adsorption. The material also showed anionic and cationic dye adsorption capacity for textile wastewater following both Langmuir and Freundlich models where BC2 had better max adsorption capacity compared to BC1, 6.519 mg.g-1 for MO and 8.612 mg.g-1 for MB.
