摘要：

An automated procedure is described for the simultaneous UV, fluorescence and electro chemical detection in series of bentazone and six phenoxy acid herbicides. A two step liquid-liquid extraction with dichloromethane giving an enrichment about a thousand fold has been used. Recovery rates after enrichment and detection limits of bentazone, 2,4 D, 2,4 DB, MCPA, MCPB, MECOPROP and DICHLORPROP in river water are given. It is concluded that the herbicides examined can be detected at levels between 20 ngl-1 without the necessity of derivatisation. © 1990 Friedr. Vieweg & Sohn Verlagsgesellschaft mbH.
