| dc.description.abstract | The adsorption-desorption behaviour of imazamox in three Punjab soils was evaluated using the batch equilibrium technique. The adsorption- desorption kinetics of imazamox were found to be a two step processand was well described by pseudo second order kinetic model. On the basis of the measured R2 values, the adsorption data fitted well in Freundlich model (R2> 0.998) followed by Langmuir (R2>0.981) followed by Temkin (R2>0.870) and D-R (R2>0.447). KFads ranged from 1.358 to 2.148 μg1−1/n g−1ml1/n indicating that imazamox has weak adsorption capacity that varied significantly with the concentration, temperature and properties of soil. KFdes was found to be higher as compared to KFads for the studied soils. Desorption of imazamox was hysteretic in all the studied soils and hysteresis coefficient varied from 0.001 to 0.015. Thermodynamic analysis showed that imazamox adsorption onto soils was a feasible, spontaneous and exothermic process which becomes more favourable at low temperature. | en_US |
