【Abstract】 The color reaction of rutin with aluminum(Ⅲ) was studied.In the presence of pH=5.6 buffer solution and CTMAB medium,rutin can reacts with aluminum(Ⅲ) to form a stable 3∶1 complex.The molar absorptivity was 4.38×10 4L·mol -1 ·cm -1 at 430nm.Beer’s law was obeyed in the range of 0～10μg/25ml.The method could be used in the determination of aluminum in environmental sample with satisfactory results.更多还原
