挥发性有机物( VOCs)量大面广、危害严重，随着对大气污染物认识的提高，VOCs污染控制上升到了一个突出位置，寻求经济高效的污染控制方法已成当务之急。本研究旨在利用微乳液和混合表面活性剂溶液对有机物的特殊增溶作用，将其作为新型吸收剂,探索吸收治理VOCs的新途径。以最典型的VOCs-"三苯"（BTEX）为处理对象，主要研究：1）根据饱和蒸气压下BTEX在微乳液和混合表面活性剂中的平衡溶解度，筛选出一系列针对BTEX的高效增溶吸收体系；2) BTEX与各吸收体系间的气液吸收平衡关系，即BTEX溶解度与温度、气相分压、吸收溶液组成与浓度三者的关系；3）吸收动力学、传质过程及其影响因素；4）吸收剂解吸性能和解吸途径。利用吸收技术成熟、通用性强的优点，克服传统液体吸收剂存在的成本高、溶剂挥发损失大、二次污染问题突出、再生途径单一等限制，为VOCs污染控制提出一种新方法，并提供理论依据和基础。

To seek ecconomical and efficient pollution control methods of volatile organic compounds(VOCs) now is an important espect of air pollution control. In order to resolve the problem of absence of effient absorbents for treating VOCs by absorption process,a novel approach for treatment of VOCs by absorption with microemulsion and mixed surfactant solutions based on the principle that water solubility of organics can be remarkablely solubilized by microemulsion and mixed surfactant solutions. The main results and conclusions obtained are the follows.. (1) The method of pseudoternary phase diagrams was adopted to stuy the solubilization rules and phase behaviors of microemulsions formed mixture of cationic surfactant and nonionic surfactants mixed with cosurfactants,toluene, salt and water. These findings can provide the selection and formulation of absorbents based on microemulsions reliable basis. . （2）It was proved that the formula of Hc=H/[1+K(X-CMC)] can be used to quantificationally characterize the gas-liquid equilibrium relationships between toluene and the typical surfactant solutions and microemulsions. A reliable method for computing the gas-liquid partition coefficients in absorption design was obtained.. (3) the mechanisms of mass transfer process and kinetics during the absorption of VOCs by typical mixed surfactant solutions and microemulsions were carefully investigated. THe influencing factors of absorption process were analyzed also. It was found that the vast majority of resistance exists in liquid film, the absorption of toluene appears as a fast peseudo-first-order reaction respect to microemulsions.. (4)the method of treating toluene-containing exhaust gas with the formation of microemulsions was verified in a a packed tower, the maximum removal of toluene can achieve 65%; the disabled absorbents can be regenerated by distillation process, and the proportion of desorption were all above 98%.. (5) The switchable surfactants with gas or electrochemistry triggers can be used to solubilize VOCs reversibly.
