Excessive iron content in human body can cause human tissue damage, skin pigmentation, liver and spleen dysfunction and other symptoms. In this paper, the reaction of Fe3+ with o-vanillin ethanol solution to form the dark blue complex was studied. O-vanillin ethanol solution has strong selectivity to Fe3+. In the range of Fe3+ concentration 0~200 μM , the ultraviolet light absorption of Fe3+ with different concentrations showed a good linear relationship with Fe3+ concentration (R=0.99299), the detection limit of o-vanillin ethanol solution on Fe3+ was about 1 M.
