Abstract
The potentiometric determination of the distribution coefficient of ph enol, 2-chlorophenol, 2-nitrophenol, 2,4-dichlorophenol and 2-methylph enol between 1.0 mol dm(-3) NaCl and five different organic solvents a t 25 degrees C is presented. An automated potentiometric system was us ed and the determination of the constants was carried out using both g raphical and numerical methods. The relevance of this study for the de velopment of supported liquid membrane (SLM) recovery systems is discu ssed.
