Antibiotics are considered as the new generation water pollutants as these disturb endocrine systems if water contaminated with antibiotics is consumed. Among many antibiotics norfloxacin is present in various natural water bodies globally. This antibiotic is considered an emerging pollutant due to its low degradation in aquatic animals. Besides, it has many side effects on human vital organs. Therefore, the present article discusses the recent advances in the removal of norfloxacin by adsorption. This article describes the presence of norfloxacin in natural water, consumption, toxicity, various adsorbents for norfloxacin removal, optimization factors for norfloxacin removal, kinetics, thermodynamics, modeling, adsorption mechanism and regeneration of the adsorbents. Adsorption takes place in a monolayer following the Langmuir model. The Pseudo-second order model represents the kinetic data. The adsorption capacity ranged from 0.924 to 1282 mg g. In this sense, the parameters such as the NFX concentration added to the adsorbent textural properties exerted a great influence. Besides, the fixed bed-based removal at a large scale is also included. In addition to this, the simulation studies were also discussed to describe the adsorption mechanism. Finally, the research challenges and future perspectives have also been highlighted. This article will be highly useful for academicians, researchers, industry persons, and government authorities for designing future advanced experiments.

吸附修复水中诺氟沙星环境的研究进展、现状与展望

抗生素被认为是新一代水污染物，因为如果饮用被抗生素污染的水，抗生素会扰乱内分泌系统。在众多抗生素中，诺氟沙星存在于全球各种天然水体中。这种抗生素由于在水生动物体内降解率较低而被认为是一种新兴污染物。此外，它对人体重要器官也有很多副作用。因此，本文讨论吸附去除诺氟沙星的最新进展。本文介绍了诺氟沙星在天然水中的存在、消耗、毒性、用于去除诺氟沙星的各种吸附剂、去除诺氟沙星的优化因素、动力学、热力学、建模、吸附机理和吸附剂的再生。吸附按照朗缪尔模型在单层中进行。伪二阶模型代表动力学数据。吸附容量范围为0.924至1282 mg g。从这个意义上说，添加的NFX浓度等参数对吸附剂的结构特性产生了很大的影响。此外，还包括大规模的固定床去除。除此之外，还讨论了模拟研究来描述吸附机理。最后，还强调了研究挑战和未来前景。本文对于院士、研究人员、行业人士和政府当局设计未来的高级实验非常有用。
