吸附方法在有效去除废水中的磷酸盐方面具有广阔的潜力,然而,它在实际应用中面临着巨大的挑战。对吸附机理的有限理解和缺乏扩大应用的评估方法是两个主要障碍。为充分实现P吸附剂的实际应用,我们回顾了先进的工具,包括密度泛函理论(DFT)和/或X射线吸收精细结构(XAFS)来阐明机理,强调了热力学和动力学在工程设计中的重要性,并提出了再生和再利用P吸附剂的策略。具体来说,我们深入研究了DFT和XAFS的利用,以深入了解吸附机制,侧重于活性位点验证和分子相互作用构型。此外,我们探索了吸附热力学和吸附动力学的精确计算方法,包括热力学平衡常数,反应堆选择,和再生,recovery,和P吸附剂的处置。我们的全面审查旨在为推进工程应用的高效P吸附剂的开发提供指导。
Adsorption method exhibits promising potential in effectively removal of phosphate from wastewater, yet it faces tremendous challenges in practical application. Limited comprehension of adsorption mechanisms and the lack of evaluation method for scaling up application are the two main obstacles. To fully realize the practical application of P adsorbents, we reviewed advanced tools, including density functional theory (DFT) and/or X-ray absorption fine structure (
XAFS) to elucidate mechanisms, underscored the significance of thermodynamics and kinetics in engineering design, and proposed strategies for regenerating and reusing P adsorbents. Specifically, we delved into the utilization of DFT and
XAFS to gain insights into adsorption mechanisms, focusing on active site verification and molecular interaction configurations. Additionally, we explored precise calculation methods for adsorption thermodynamics and adsorption kinetics, encompassing thermodynamic equilibrium constants, reactor selection, and the regeneration, recovery, and disposal of P adsorbents. Our comprehensive review aims to serve as a guiding light in advancing the development of highly efficient P adsorbents for engineering applications.
