Evaluation of semi permeable membranes for determination of organic contaminants in drinking water
1975
Abstract A separation and concentration scheme has been developed for trace organics in drinking water. The retention of a particular solute by a polymer membrane is related not only to the physical interactions such as size but also is dependent upon attractive forces which are normally included in the solubility of the solute in the membrane phase. Solubility parameters were used for projections of class and specific separations with cellulose acetate and ethyl cellulose membranes. These projections have been compared with the transport occurring in the absence of hydraulic flux and also with transport occurring when large hydraulic fluxes are present.
