Abstract
In this paper, the distribution data were thermodynamically analyzed f or the extraction of zinc(II) from relatively concentrated chloride so lutions with di-n-butyl butylphosphonate (DBBP) on the basis of the la w of mass action. A method employing the Meissner equations for stoich iometric activity coefficient estimations was found to be effective fo r the explanation of the distribution data. The thermodynamic equilibr ium constant for the extraction reaction was determined and the dimeri zation (self-association) constant of DBBP was also estimated at 298 K .
