Boron overabundance in aquatic environment raises severe concerns about the environment and human health because it is toxic to various crops and induces many human and animal diseases with long-term consequences. In response to the boron pollution of water resources and the difficulty of eliminating boron from water for production and living purposes, this article summarizes the progress in research on boron removal technology, addressing the following aspects: (1) the reasons for the difficulty of removing boron from water (boron chemistry); (2) ecological/biological toxicity and established regulations; (3) analysis of different existing processes (membrane processes, resin, adsorption, chemical precipitation, (electric) coagulation, extraction, and combined methods) in terms of their mechanisms, effectiveness, and limitations; (4) prospects for future studies and possible improvements in applicability and recyclability. The focus of this paper is thus to provide a comprehensive summary of reported deboronation processes to date, which will definitely identify directions for the development of boron removal technology in the future.
硼在水生环境中的过度富集引起了人们对环境和人类健康的严重关注,因为它对各种作物都具有毒性,并会导致许多人类和动物疾病,产生长期影响。针对水资源的硼污染以及生产和生活用水除硼的困难,本文总结了除硼技术的研究进展,主要涉及以下几个方面:(1)从硼化学的角度探讨了水中除硼困难的原因;(2)硼的生态/生物毒性及已建立的规定;(3)分析了不同现有工艺(膜工艺、树脂、吸附、化学沉淀、(电)凝聚、萃取以及组合方法)的作用机制、有效性和局限性;(4)对未来研究的展望以及在适用性和可回收性方面可能的改进。因此,本文的重点是对迄今为止报道的除硼工艺进行全面总结,这必将为未来的除硼技术发展指明方向。
