The effect of constant magnetic field on the color reaction of Fe (Ⅲ) -KSCN-RhB-acacia gum system was studied. It was found that in a certain range, the stability of the magnetic field can significantly improve the sensitivity of the multi-complex system color reaction. The molar ratio of c (K 2 SO 4) to 0 0 2 0 mol L, c (KSCN) to 0 96 mol L and c (RhB) to 4.4 × 10 5 mol L and the mass fraction of gum arabic to 0. 05% , The steady magnetic field with magnetic induction of 75mT can increase the color developing sensitivity at the maximum absorption wavelength of 590nm by 46.7% and the color developing sensitivity at the wavelength of 610nm by more than 10% Mechanism of Color Sensitivity of Micelle Complexes.
