摘要(Abstract):

鲁米诺是一种分子发光探针,在三价铬离子的存在下与过氧化氢可以产生化学发光,当实验条件恰当时,在一定的范围内三价铬离子浓度与化学发光强度成正比,将此测定原理应用于中草药微量铬的测定效果满意。
Luminol which may serve as a Molecular luminescence probe. causes chemiluminescence together with H_2O_2 in the presence of Cr~(3+). Under suitable experimental conditions and within a certain linear range, the concentration of Cr~(3+) is in direct proportion to chemiluminescence strength. On the principle of this, we tested microchromium in Chinese herbal medicine. The reasult was satisfactory.
