Abstract: The formation of the ion assoc. of [AuCl4]- with carbethoxypentadecyltrimethylammonium bromide (Septonex) was studied. A new spectrophotometric method for the detn. of Au(III) at μg/cm3 levels by using Septonex was developed; the absorbance of the ion assoc. is measured at 332 nm in pH 0.1-1.0 soln.
