Fig. 6. Influence of kinetics type on accuracy of modeling imazaquin desorbing from soil, averaged over 24-, 72-, 168-h incubation times before desorption. Initial imazaquin–soil concentration was 17.8 µmol kg^–1. Flow rate for all treatments was 1.0 mL min^–1. Error bars equal ±1 standard deviation within each fraction of effluent.
