Studying the kinetics of important solvent extraction reactions and             identifying the rate limiting step has led to system modifications to           achieve dramatically improved results.  This work served to verify that         chemical reactions and not mass transfer were the system bottlenecks            for important systems already studied.  Future research will produce            rate data for additional systems and lead to general development to             point to general methods to improve other systems in the difficult              platinum group.  In addition to quantitative measurements with a series         of complex extraction agents, hollow fiber membrane filter assemblies           will be studied to achieve alternative methods for separation.
