Removal of 12 organic compounds containing chloro-chemicals from an aqueous solution has been carried out using solvent sublation.The removal was obtaind to compare with the experimental results. The removal rate of organic compounds is strongly concerned with the physical and chemical properties of their compounds,such as solubility,vapor pressure,surface tension and distribution coefficient between the aqueous and organic phase.The experimental removal rate is evaluated and discussed concernig the physical and chemical properties of the compounds to be removed. A model for the removal mechanism is constracted by considering several terms such as adsorption on bubble,entrainment with boudary layer of bubble,vaporization to bubble and mass transfer to the organic solvent in the upper part of column.The calculated value is in good agreement with the experimental results.Accoding to the removal model,contribution percentage of the above terms is estimated and then it is clarified which terms are significant for the removal of the organic compounds with different chemical properties.http://ci.nii.ac.jp/naid/10002284277

Removal of 12 organic compounds containing chloro-chemicals from an aqueous solution has been carried out using solvent sublation. The removal mechanism of solvent sublation was studied, from which the calculated value for removal was obtaind to compare with the experimental results.<BR>The removal rate of organic compounds is strongly concerned with the physical and chemical properties of their compounds, such as solubility, vapor pressure, surface tension and distribution coefficient between the aqueous and organic phase. The experimental removal rate is evaluated and discussed concerning the physical and chemical properties of the compounds to be removed. A model for the removal mechanism is constracted by considering several terms such as adsorption on bubble, entrainment with boundary layer of bubble, vaporization to bubble and mass transfer to the organic solvent in the upper part of column. The calculated value is in good agreement with the experimental results. According to the removal model, contribution percentage of the above terms is estimated and then it is clarified which terms are significant for the removal of the organic compounds with different chemical properties.
