氨基苯甲酸-过氧化氢-铁(Ⅱ)化学发光体系的研究

STUDY ON THE CHEMILUMINESCENT SYSTEM OF AMINOBENZOIC ACID-HYDROGEN PEROXIDE-IRON(II)

报道了氨基苯甲酸 -过氧化氢 -铁 (II)化学发光体系 ,研究了共存物质、pH及试剂浓度对体系的影响 .同等实验条件下氨基的取代位次 (邻、间、对 )不同所获得的发光强度有很大的差别 .本文给出了该体系化学发光的可能机理 .

Aminobenzoic acid hydrogen peroxide iron(II) system was investigated, and. the effects of foreign substances, pH, and the concentration of the reagent were studied. The result showed that the intensity of chemiluminescence for o,m,p aminobenzoic acids is quite different under same conditions. The possible mechanism of the chemiluminescence in the system has been supplied. This method has been applied to the analysis of products with satisfactory results.
