摘　　要：在碱性条件下,铁氰化钾(K3Fe(CN)6)氧化鲁米诺(Luminol)产生化学发光,间苯二酚对该体系的化学发光有显著的增强作用.基于此,并结合流动注射技术,建立了测定间苯二酚的新方法.该方法具有很高的灵敏度,检测限为5.7×10-9kg/L(IUPAC),线性范围为1.0×10-8～1.0×10-6kg/L,对1.0×10-7kg/L间苯二酚标准溶液平行测定11次,其相对标准偏差为3.8%.A novel chemiluminescence method coupled with flow injection technique for determination of resorcinol is developed in the paper. It is based on the enhancement of resorcinol on the chemiluminescence reaction of luminol with ferricyanide in sodium hydroxide medium. The chemiluminescence intensity to the concentration of resorcinol is linear range from 1.0×10 -8 to 1.0×10 -6kg/L. The RSD for 1.0×10 -7kg/L ketofiten is 3.8% (n=11), and the detection limit is 5.7×10 -9kg/L. This method has successfully been applied to the determination of resorcinol in waste water.
