A sensitive spectrophotometric method for the determination of gold (III) with 5-p-dimethylaminocinnamylidene-1-phenyl-2-thiobarbituric acid (DACTB) is described. DACTB reacts easily with gold (III), forming a blue complex in diluted hydrochloric acid which can be extracted with chloroform. The chloroform solution of the complex has an absorption maximum at 622 nm against a reagent blank and shows a constant absorbance over the final hydrochloric acid concentration range of 0.02-0.07 M. Beer's law holds over the range of 0.1-0.9 μg/ml of gold (III) at 622 nm. The molar extinction coefficient of the complex is 1.1×105·l·mol-1·cm-1. The coefficient of variation was 1.34% for 0.5 μg/ml of gold (III). The coexistence of cations such as Pd (II), Fe (II), Ce (IV), and Mn (VII) interfered considerably with the determination.
