摘　　要：基于氧乐果的水解反应和巯基化合物 铈(Ⅳ)的化学发光反应,以罗丹明B作为增敏剂,建立了痕量氧乐果的流动注射 化学发光分析方法。该方法的线性范围和检出限分别为0.04～14.00mg/L和0.02mg/L,相对标准偏差(n=11,ρ=1.00mg/L)为0.9%。该方法已用于废水水样的分析。A new flow-injection chemiluminescence (CL) method for the determination of omethoate is described. The method is based on the hydroLysis of omethoate and the CL reaction of thiol-containing compound with Ce(Ⅳ) in acidic condition sensitized by the fluorescent dye Rhodamine B. The linear range and detection limit of the method is 0.04～14.00 and 0.02 mg/L. The relative standard deviation (n=11, ρ=1.00 mg/L) is 0.9%. The method has been applied to the determination of trace omethoate in environmental water samples with satisfactory results.
