In this study, preparation of Phragmites australis activated carbon (PAAC) was optimized and applied for the removal of hydroquinone from aqueous solution. The Box-Behnken surface design (3³) was used to statistically visualize the interactions among microwave power (A), microwave radiation time (B) and the ingredient ratio (C) (H₃PO₄: P. australis powder, in g). The desirability function was utilized to simultaneously optimize the multi-response indicators. A regression analysis showed that the experimental data of BBD optimization experimental results fit well to a quadratic model. PAAC was characterized according to its morphology, structure and composition. Dynamic adsorption data showed that the best fit was obtained by a pseudo-second-order model and the Freundlich isotherm model. The maximum adsorption capacity for hydroquinone adsorption onto PAAC was 156.25 mg/g at 30 ℃ and the adsorption mechanism may be attributed to multi-layer surface and chemisorption via donor-acceptor and coupling interaction of the electron. The present study showed that PAAC has the potential for use as a biosorbent for the adsorption treatment of water pollutants.

在这项研究中，对芦苇活性炭（PAAC）的制备进行了优化，并将其用于从水溶液中去除对苯二酚。Box-Behnken表面设计（3 ³）用于统计可视化微波功率（A），微波辐射时间（B）和成分比（C）（H ₃ PO ₄：P. australis）之间的相互作用粉，以克计）。期望功能用于同时优化多响应指标。回归分析表明，BBD优化实验结果的实验​​数据很好地拟合了二次模型。根据PAAC的形态，结构和组成对其进行表征。动态吸附数据表明，最佳拟合是通过拟二阶模型和Freundlich等温模型获得的。在30℃时，对苯二酚在PAAC上的最大吸附能力为156.25 mg / g，其吸附机理可能是由于多层表面以及通过供体-受体的化学吸附和电子的耦合作用。本研究表明，PAAC具有作为生物吸附剂用于水污染物吸附处理的潜力。
