【Abstract】 The kinetic spectrophotometric determination of trace silver is presented by means of the catalytic reaction between K4Fe（CN）6 and o-phenanthro-line（o-phen）. The molar absorbance coefficience, ε, is 1.11×10⁷L·mol^-1·cm^-2and the linear range is 0.005 to 0.12 μg Ag+/20ml. The method has been used for the determination of silver in geochemical samples with satisfactory results.更多还原
