摘要
磷是引起水体富营养化的限制性因子,同时,由于凹凸棒石具有良好的吸附性能,因此,利用其吸附净化液相磷素成为研究的热点。本文综合分析国内外学者对凹凸棒石研究成果基础之上,介绍了凹凸棒石的矿物学特性,详细阐述了凹凸棒石吸附液相磷素机理。文章首次重点探讨了吸附过程的关键影响因素及酸碱度对磷素净化效果的复合影响机制,同时,讨论了吸附动力学和热力学以及解吸过程,这对凹凸棒石在环境领域的应用具有重要的科学理论价值及实际意义。
Phosphorus is considered to be the restrictive element in water eutrophication. Meanwhile, palygorskite has been applied in decontaminating phosphorus due to the excellent adsorptive characteristics. Therefore, the research on the feasibility of adopting palygorskite in phosphorus removal from aqueous solutions is getting more attractive. This investigation assessed the mineralogical characteristics of palygorskite clay which was based on the analysis of related literatures. The current work researched the mechanism of palygorskite adsorbing phosphorus from aqueous solutions. The key influencing factor, power of hydrogen value, was put forward for the course of adsorption. The authors summarized the kinetics and thermodynamics studies which covers the theoretical and practical significance for the application of palygorskite in environmental areas.
