Abstract

A procedure has been developed for the determination of quinclorac, bentazone, 2,4‐D, clomazone, and propanil residues in surface and agriculture waters by SPE and HPLC‐UV. The method was validated and was applied for levels between 0.1 and 0.5 g/L, after a 500‐fold pre‐concentration. Average recoveries ranged from 85.7 to 109.8% with overall relative standard deviations of 1.8 to 13.4%.
