Steroidal estrogens (SEs) remain one of the notable endocrine disrupting chemicals (EDCs) that pose a significant threat to the aquatic environment in this era owing to their interference with the normal metabolic functions of the human body systems. They are currently identified as emerging contaminants of water sources. The sources of SEs are either natural or synthetic active ingredients in oral contraceptive and hormonal replacement therapy drugs and enter the environment primarily from excretes in the form of active free conjugate radicals, resulting in numerous effects on organisms in aquatic habitats and humans. The removal of SEs from water sources is of great importance because of their potential adverse effects on aquatic ecosystems and human health. Adsorption techniques have gained considerable attention as effective methods for the removal of these contaminants. A systemic review and bibliometric analysis of the application of adsorption for sequestration were carried out. Metadata for publications on SE removal utilizing adsorbents were obtained from the Web of Science (WoS) from January 1, 1990, to November 5, 2022 (107 documents) and Scopus databases from January 1, 1949, to November 5, 2022 (77 documents). In total, 137 documents (134 research and 4 review articles) were used to systematically map bibliometric indicators, such as the number of articles, most prolific countries, most productive scholars, and most cited articles, confirming this to be a growing research area. The use of different adsorbents, include activated carbon graphene-based materials, single and multi-walled carbon nanotubes, biochar, zeolite, and nanocomposites. The adsorption mechanism and factors affecting the removal efficiency, such as pH, temperature, initial concentration, contact time and adsorbent properties, were investigated in this review. This review discusses the advantages and limitations of different adsorbents, including their adsorption capacities, regenerative potential, and cost-effectiveness. Recent advances and innovations in adsorption technology, such as functionalized materials and hybrid systems, have also been highlighted. Overall, the bibliographic analysis provides a comprehensive overview of the adsorption technique for the removal of SEs from other sources, serving as a valuable resource for researchers and policymakers involved in the development of efficient and sustainable strategies to mitigate the effects of these emerging contaminants.
甾体雌激素（SEs）仍然是显著的内分泌干扰化学物质（EDCs）之一，在这个时代，它们因干扰人体系统的正常代谢功能而对水生环境构成重大威胁。它们目前被确定为水源中的新兴污染物。SEs的来源要么是口服避孕药和激素替代疗法药物中的天然或合成活性成分，主要以活性游离共轭自由基的形式通过排泄物进入环境，从而对水生栖息地的生物和人类产生诸多影响。由于SEs对水生生态系统和人类健康具有潜在的不利影响，因此从水源中去除SEs至关重要。吸附技术作为去除这些污染物的有效方法已受到广泛关注。本文对吸附法用于螯合SEs的应用进行了系统综述和文献计量分析。利用吸附剂去除SEs的相关出版物的元数据，从1990年1月1日至2022年11月5日的科学网（WoS）（107份文献）以及1949年1月1日至2022年11月5日的Scopus数据库（77份文献）中获取。总共使用了137份文献（134篇研究论文和4篇综述文章）来系统绘制文献计量指标，如文章数量、最多产的国家、最多产的学者以及被引用最多的文章，证实这是一个不断发展的研究领域。使用的不同吸附剂包括活性炭、基于石墨烯的材料、单壁和多壁碳纳米管、生物炭、沸石和纳米复合材料。本综述研究了吸附机制以及影响去除效率的因素，如pH值、温度、初始浓度、接触时间和吸附剂性能。本综述讨论了不同吸附剂的优点和局限性，包括它们的吸附容量、再生潜力和成本效益。还强调了吸附技术的最新进展和创新，如功能化材料和混合系统。总体而言，文献分析全面概述了从其他来源去除SEs的吸附技术，为参与制定有效且可持续策略以减轻这些新兴污染物影响的研究人员和政策制定者提供了宝贵资源。
