Antibiotic residues have been extensively identified in diverse aquatic environments, posing significant health risks to both humans and animals, while also presenting challenges to the environment. Consequently, the imperative need to effectively removal antibiotics from the environment has become a very importance issue. In this study, response surface methodology with central composite design was employed to systematically investigate the effects of key process parameters, on the removal of cefotaxime (CTX) from hospital wastewater using pistachio sells based activated carbon modified with FeCl. The modified activated carbon was synthesized using a thermochemical method and characterized by analytical techniques including FE-SEM, FTIR, XRD, pH, and BET analysis, which demonstrated its remarkable physicochemical properties. Maximum removal efficiency of 99.1% was obtained via the optimal values of 45 mg L of initial CTX concentration, solution pH 7, and 200 mg L of Fe@ACP dosage, 56 min of reaction time through adsorption process. According to the results, the non-linear Langmuir isotherm model (R = 0.9931) and non-linear second order kinetic model (R = 0.9934) are suitably described the monolayer and chemisorption of CTX adsorption. The maximum adsorption capacity of Fe@ACP is 651.6 mg g. Consequently, the developed treatment process revealed successful performance for quick and efficient removal of CTX by Fe@ACP. The developed process introduced an economic and green approach for the comprehensive utilization of agricultural waste resources used for environmental pollution control.
抗生素残留已在多种水生环境中被广泛检测到，这对人类和动物都构成了重大健康风险，同时也给环境带来了挑战。因此，从环境中有效去除抗生素的迫切需求已成为一个非常重要的问题。在本研究中，采用中心复合设计的响应面方法，系统地研究了关键工艺参数对使用氯化铁改性的开心果壳基活性炭去除医院废水中头孢噻肟（CTX）的影响。改性活性炭采用热化学方法合成，并通过场发射扫描电子显微镜（FE-SEM）、傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、pH值和比表面积（BET）分析等分析技术进行表征，结果表明其具有显著的物理化学性质。通过吸附过程，当初始CTX浓度为45 mg/L、溶液pH值为7、Fe@ACP投加量为200 mg/L、反应时间为56分钟时，获得了99.1%的最大去除效率。结果表明，非线性朗缪尔等温线模型（R = 0.9931）和非线性二级动力学模型（R = 0.9934）能较好地描述CTX吸附的单层吸附和化学吸附。Fe@ACP的最大吸附容量为651.6 mg/g。因此，所开发的处理工艺显示出通过Fe@ACP快速高效去除CTX的成功性能。所开发的工艺为利用农业废弃物资源进行环境污染控制引入了一种经济且绿色的综合利用方法。
