摘要：
A simplified, high-performance liquid chromatography (HPLC) method of the simultaneous measurement of the herbicides tebuthiuron and hexazinone was developed. Separation was achieved on a Nova-Pak(R) phenyl (4-mu-m) 10 x 0.8 cm column with methanol-water (50:50 v/v) as eluent and on-line detection at 254 nm for tebuthiuron and 249 nm for hexazinone. At a flow-rate of 2.5 ml min-1, the retention times were approximately 4.5 and 6.3 min for tebuthiuron and hexazinone, respectively. The procedure was used successfully for the analysis of residues of these herbicides in soil and plant tissues. A comparison with published procedures for the individual analysis of tebuthiuron and hexazinone is presented.
