摘要: 介绍了水中含磷的危害及通过比较选择吸附法作为一种高效、低能耗的除磷方法,吸附剂及其特点和金属类氧化物、黏土矿石类、活性炭吸附材料的吸附原理。详细阐述了反应温度、反应时间、反应pH值、共存离子对矿石黏土类物质和铁锆化合物吸磷过程的影响:反应温度主要通过影响分子热运动从而影响到吸附材料吸磷效果;对任何吸附材料吸磷都需要一定的反应时间来达到最佳效果;反应pH值主要通过影响溶液中离子浓度、种类及吸附材料表面所含的离子与其反应从而影响到吸附材料吸磷效果;共存离子的存在可能会提高库仑力和磷酸盐活性部位竞争力。同时也阐述了吸附剂用量、磷的初始浓度、电解质、吸附材料粒径对吸磷效果的影响。今后对吸附磷材料的研究应重点关注改性材料及复合材料。

Abstract: Removing phosphorus from water through adsorption is highly efficient with low energy consumption. In this article, the characteristics of adsorbents and the adsorption mechanisms of metal oxides, clay mineral, and activated carbon are introduced. The effects of reaction temperature, reaction time, pH value, and coexisting ions on the adsorption process of mineral clay and iron zirconium compounds are expounded: reaction temperature mainly affects the molecular heat movement, which further affects the adsorption effect; a certain reaction time is always needed to reach the optimum effect; pH value mainly has an influence on ion concentration, ion type and ion reaction; coexisting ions could improve the Coulomb force and the competitiveness of phosphate’s active site. Moreover, the effects of adsorbent amount, phosphorus’ initial concentration, electrolyte and adsorbent’s particle size on the phosphorus adsorption are also described. Modified materials and composite materials are research focuses in the future.

Key words: mineral clay, iron oxides, zirconium iron compounds, adsorption, phosphate
