PM2.5对大气环境及人类健康造成了较严重的危害,对PM2.5有效脱除净化技术的研究迫在眉睫。主要阐述了PM2.5与吸附相关的理化特性,对其在多孔吸附材料上的主要吸附力进行了探讨,表明颗粒越小,与固体表面距离越近,所受到的吸附力越大,颗粒所受吸附作用越明显;此外,吸附材料种类、空气湿度与压力亦为重要的影响因素。使用多孔材料对空气中的细颗粒物进行吸附过滤实验,并进行了简要分析。

PM2.5 has posed severe hazards to atmospheric environments and human health .It is urgent to develop effective technologies for PM2.5 removal.This paper clarifies the adsorptive characters of PM 2.5 on porous materials.The dominant adsorptive forces are discussed , showing that the adsorptive forces are larger and the adsorption effect on particles are more evident when the particle is of a smaller size with a smaller distance from the solid surface .Additionally , the material type , air humidity and pressure are also significant factors .A brief analysis is conducted based on filtration experiments towards fine ambient particles using different materials .
