微量铬在Cr~(3+)-Luminol(鲁米诺)-H_2O_2体系中,自由铬(Ⅲ)离子在碱性介质的氧化反应有催化作用,在反应过程中会发出具有一定波长的光,而光的强度与铬(Ⅲ)离子
Trace chromium In the Cr ~ (3 +) - Luminol-H_2O_2 system, the free chromium (Ⅲ) ion catalyzes the oxidation reaction in alkaline medium and emits a certain wavelength of light during the reaction. The intensity of light and chromium (III) ions
