Adsorption of hydroxychloroquine (HCQ) onto HPO-activated (Stackhouse) C. Agardh (derived from algal biodiesel industry waste) biochar was investigated via batch experiments and mathematical models. The activated biochar (BC-H) was produced in a single step by using the microwave irradiation method. Thus, it was obtained with a low cost, energy efficiency and by promoting clean production processes. BC-H exhibited a remarkable adsorption efficiency (98.9%) and large surface area (1088.806 m g) for removal of HCQ. The Langmuir isotherm and the pseudo-second-order kinetic models were the best fit for the equilibrium adsorption and kinetics experiments, and the maximum monolayer adsorption capacity (qmax) was found to be 353.58 µg g. Additionally, the experiments with real wastewater showed that BC-H's ability to adsorb HCQ was not affected by competitive ions in the water. The Taguchi orthogonal array (L16 OA) experimental design was applied for the effective cost optimization analyses of the adsorption process by considering four levels and four controllable factors (initial pH, HCQ concentration, amount of adsorbent and contact time). Scanning electron microscopy, Fourier transform infrared spectroscopy and Brunauer-Emmett-Teller analyses were used for characterizing the adsorbent. The findings showed that BC-H can be used as an effective and low-cost adsorbent in the removal of HCQ from water.

通过批量实验和数学模型研究了羟基氯喹（HCQ）在经HPO活化（Stackhouse）的阿加德氏衣藻（源自藻类生物柴油工业废料）生物炭上的吸附情况。活化生物炭（BC - H）采用微波辐照法一步制备而成。因此，其制备成本低、能源效率高且促进了清洁生产过程。BC - H在去除HCQ方面表现出显著的吸附效率（98.9%）和较大的表面积（1088.806 m²/g）。朗缪尔等温线和准二级动力学模型最适合平衡吸附和动力学实验，最大单层吸附容量（qmax）为353.58 μg/g。此外，实际废水实验表明，水中的竞争离子不会影响BC - H吸附HCQ的能力。通过考虑四个水平和四个可控因素（初始pH值、HCQ浓度、吸附剂用量和接触时间），采用田口正交阵列（L16 OA）实验设计对吸附过程进行有效成本优化分析。利用扫描电子显微镜、傅里叶变换红外光谱和布鲁诺尔 - 埃米特 - 泰勒分析对吸附剂进行表征。研究结果表明，BC - H可作为一种有效且低成本的吸附剂用于去除水中的HCQ。
