摘　　要：在碱性条件下,Ag(Ⅲ)配合物可以氧化鲁米诺产生化学发光,西维因可以增强其发光强度,基于此结合流动注射建立了Ag (Ⅲ)配合物-鲁米诺化学发光体系测定西维因的方法。考察了鲁米诺、Ag(Ⅲ)配合物及NaOH浓度对发光强度的影响,在最佳实验条件下,西维因质量浓度在30~800 ng/L范围内与发光信号增加的强度成良好的线性关系,相关系数R=0.9954,检出限为2.72 ng/L。对质量浓度为50 ng/L的西维因平行测定9次,计算其相对标准偏差(RSD)为3.5%。In alkaline solution,the Ag(Ⅲ) complex-luminol chemiluminescent system which was applied to the determination of carbaryl,based on the enhancing effect of carbaryl on the chemiluminescence reaction of luminol with [Ag( HIO6)2]5- was reported. The main factors affecting the determination were investigated. Under the optimum conditions,the enhance of CL intensity was proportional to the concentration of carbaryl in the range of 30-800 ng/L. The detection limit was 2. 72 ng/L,with a relative standard deviation of 3. 5% for 9 times measurement to 50 ng/L carbaryl.
