摘要：

In the present paper, we report on the effect of magnetic field on the colour reaction of Fe(III)-KSCN-Rhodamine B-arabic gum polycomponent coordination compound micelle system. It is indicated that under the optimized conditions of 2.0 x 10(-2) mol l(-1) H2SO4, 9.6 X 10(-2) mol l(-1) KSCN, 4.4 x 10(-5) mol l(-1) Rhodamine and 0.05% arabic gum, the molar absorptivity of this system at maximum wavelength of 590 nm, epsilon(max), was raised from 2.52 x 10(5) to 3.70 x 10(5), i.e. its sensitivity was increased by 46.7% after magnetization for 5 min at a 75 mT magnetic field. The mechanism of the effect of magnetic field on the colour reaction was discussed.
