✦ Synopsis

The capabilities of a combined liquid-liquid extraction/spectrophotometric method for the trace determination of gold in geological samples are presented. After extraction with ethyl acetate, gold in the extracts is quantified as tetrachloroaurate with the multicomponent data-processing programs inherent in a diode-array u.v.-visible spectrophotometer.

This method has an overall detection limit of 0.4 rg Au g' sample and a combined extraction/measurement imprecision of less than 512%.
