Abstract

This work investigated the efficiency of CoFe₂O₄ nanoparticles in removing diclofenac and naproxen drugs from aqueous solutions. At first, the Taguchi method was performed to choose the most important factors among the investigated factors affecting the removal efficacy of these drugs. Afterward, the optimal conditions of the effective factors were investigated and modeled by the central composite design-based response surface method. The results revealed that the maximum drug removal was obtained at pH = 7, temperature of 25 °C, adsorbent dosage of 215 mg, sonication time of 21 min, and diclofenac and naproxen concentrations of 15 mg L⁻¹. The removal efficacy of diclofenac and naproxen under these optimal conditions was 99.42 % and 95.11 %, respectively. Based on the results, it is concluded that CoFe₂O₄ nanoparticles can be applied as an easy-available and effective adsorbent for removing diclofenac and naproxen from water samples.

基于化学计量学方法的双氯芬酸和萘普生高效去除模型的建立和优化

本研究探讨了 CoFe2O4 纳米粒子去除水溶液中双氯芬酸和萘普生药物的效率。首先，采用田口方法从影响这些药物去除效果的考察因素中选择最重要的因素。然后，采用基于中心复合设计的响应面法对有效因素的最佳条件进行了研究和建模。结果表明，在 pH = 7、温度为 25 °C、吸附剂用量为 215 毫克、超声时间为 21 分钟、双氯芬酸和萘普生浓度为 15 毫克/升时，药物去除率最大。在这些最佳条件下，双氯芬酸和萘普生的去除率分别为 99.42 % 和 95.11 %。根据这些结果，可以得出结论：CoFe2O4 纳米粒子可作为一种易得且有效的吸附剂，用于去除水样中的双氯芬酸和萘普生。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
