摘　　要：基于在稀硫酸介质中,痕量间苯二酚对铜(Ⅱ)催化过氧化氢氧化丁基罗丹明B的反应具有显著的阻抑作用,建立了动力学荧光法测定痕量间苯二酚的新方法。在最佳实验条件下,测定间苯二酚的线性范围为0.005～1.8 mg/L,检出限为0.0034 mg/L,并考察了二十多种物质的干扰情况。该方法用于环境水样中间苯二酚的测定,加标回收率在98%～104%之间,相对标准偏差为1.9%～2.3%。A new kinetic fluorimetry method has been proposed for the determination of trace resorcinol.The method based on the activation effect of resorcinol inhibitory the catalytic oxidation of butyl-rhodamine B by hydrogen peroxide in the presence of Copper（Ⅱ）in dilute sulfuric acid solution.Under the optimum conditions the limit for the determination of resorcinol is found to be 0.0034mg /L.The liner rang is 0.005～1.8mg /L.The influence of common ions and organic compounds on the determination was investigated.The method has been applied to determining resorcinol in environmental water samples,the recoveries were in range of 98%～104%,with the RSDs of 1.9%～2.3%.
