Abstract
The distribution equilibrium: AuCl 4 -+(Bu 4N +, ClO 4 -)HCCl 3 ⇌ (Bu 4N +, AuCl 4 -)HCCl 3+C1O 4 -, has been examined. With acidic aqueous chloride solutions in which -log ([H +] [Cl -]) 1 2 is greater than 2, the apparent equilibrium constant, K A, is a constant equal to the equilibrium constant of the distribution reaction above; a value of 2.88·10 3 was obtained. Combination of the extraction with a direct spectrophotometric determination of AuCl 4 - in chloroform at 312 nm provides a simple, rapid, and accurate analytical method for the separation and determining of gold in the μg-range.
