【Abstract】 The conditions of color reaction of induum with piperonal fluorone was studied.The maximum absorption of this system is at 550 nm with molar absorptivity of 1.15×105 L·mol -1 ·cm -1 .Beer’s law is obeyed in the range of 0～14 μg/25 mL.The method with satisfactory result can be applied to the determination of indium.更多还原
