摘要

药物污染是一类值得注意的新兴污染物。这些生物活性化合物对人类健康和环境造成一系列有害影响。这是由于它们的耐火性能,较差的生物降解性和伪持久性。制药工业的大规模生产以及随后在医院、社区卫生中心和兽医设施等的广泛使用,大大增加了各种环境隔间中药物残留的发生率。目前正在评估几种技术,以消除水环境中的药物化合物(PCs)。其中,吸附法因其操作简单、成本低而成为最可行的处理方法。因此,目前正在进行密集的研究和开发工作,以开发廉价的吸附剂,以有效地减少pc。尽管近年来已经研究了许多吸附剂用于去除pc,但生物炭基吸附剂由于其良好的比表面积、可调节的表面化学、可扩展的生产和环境友好的性质,已经获得了巨大的科学关注,以从水性基质中去除pc。本文就生物炭在废水中脱除pc的最新研究进展作一综述。此外,确定了领域知识的基本知识差距,并制定了新的战略研究指导方针,以进一步推进这一有前途的可持续发展方法。

Biochar-mediated removal of pharmaceutical compounds from aqueous matrices via adsorption

Biochar-mediated removal of pharmaceutical compounds from aqueous matrices via adsorption

Pharmaceutical is one of the noteworthy classes of emerging contaminants. These biologically active compounds pose a range of deleterious impacts on human health and the environment. This is attributed to their refractory behavior, poor biodegradability, and pseudopersistent nature. Their large-scale production by pharmaceutical industries and subsequent widespread utilization in hospitals, community health centers, and veterinary facilities, among others, have significantly increased the occurrence of pharmaceutical residues in various environmental compartments. Several technologies are currently being evaluated to eliminate pharmaceutical compounds (PCs) from aqueous environments. Among them, adsorption appears as the most viable treatment option because of its operational simplicity and low cost. Intensive research and development efforts are, therefore, currently underway to develop inexpensive adsorbents for the effective abatement of PCs. Although numerous adsorbents have been investigated for the removal of PCs in recent years, biochar-based adsorbents have garnered tremendous scientific attention to eliminate PCs from aqueous matrices because of their decent specific surface area, tunable surface chemistry, scalable production, and environmentally benign nature. This review, therefore, attempts to provide an overview of the latest progress in the application of biochar for the removal of PCs from wastewater. Additionally, the fundamental knowledge gaps in the domain knowledge are identified and novel strategic research guidelines are laid out to make further advances in this promising approach towards sustainable development.
