摘要

利用花生壳这种低成本的农业废弃物来消除水溶液中的酸性蓝 25 染料。在批量吸附试验中对接触时间、吸附剂浓度、粒度和吸附剂质量进行了研究。根据平衡模型和动力学模型对吸附过程进行了研究。根据吸附动力学结果，在所有实验条件下，吸附过程与伪二阶模型的一致性较好，回归系数值均为 1。用 Freundlich、Langmuir 和 Temkin 模型来描述吸附等温线，平衡数据与 Freundlich 等温线一致，回归系数值 R2 较大。根据研究结果，花生壳在去除水溶液中的酸性蓝 25 染料方面更为经济、廉价、可行和有效。

Peanut Shell as a Natural Adsorbent for the Removal of Acid Blue 25 from Aqueous Solution

Apeanut shell was used as a low-cost agricultural waste to eliminateacid blue 25 dye from an aqueous solution. Contact time, sorbate concentration, particle size, and sorbent mass were all investigated in batch sorption tests. The sorption process was investigated in terms of equilibrium and kinetics models. The sorption process is better in agreement with the pseudo-second-order model, with a greater regression coefficient value of 1 under all experimental conditions, according to adsorption kinetic results. The models of Freundlich, Langmuir and Temkin were used to describe the isotherms of adsorption, and equilibrium data was consistent with Freundlich isotherm with a higher regression coefficient value, R2. Based on the findings, the peanut shell is much more economical, cheap, viable, and very effective for the removal of acid blue 25 dye from aqueous solution.

期刊介绍： First published in 1995, the journal Environmental Research, Engineering and Management (EREM) is an international multidisciplinary journal designed to serve as a roadmap for understanding complex issues and debates of sustainable development. EREM publishes peer-reviewed scientific papers which cover research in the fields of environmental science, engineering (pollution prevention, resource efficiency), management, energy (renewables), agricultural and biological sciences, and social sciences. EREM’s topics of interest include, but are not limited to, the following: environmental research, ecological monitoring, and climate change; environmental pollution – impact assessment, mitigation, and prevention; environmental engineering, sustainable production, and eco innovations; environmental management, strategy, standards, social responsibility; environmental economics, policy, and law; sustainable consumption and education.
