Description of key information


Preliminary test showed that:

-         the time necessary to reach adsorption equilibrium was 2 hours for all the tested soils;

-         four cycles of desorption were necessary to find negligible amounts to be released;

-         IR5878 was substantially stable during the adsorption step.

Advanced test: based on the results of the Preliminary test, the incubation time was 2 hours for all the tested soils. The amount of adsorbed IR5878 was 43.35%, 54.09%, 46.63% and 46.51% as percentage mean value respectively in B-1, G-2, M-2 and VM-1 soil. At the end of the desorption cycles, the amount of desorbed IR5878 was 50.35%, 51.20%, 39.21% and 73.70% as percentage mean value respectively in B-1, G-2, M-2 and VM-1 soil. The data of adsorption isotherms fitted very well (r2> 0.97) with Freundlich equation. Mass balance was ≥ 93%. The adsorption-desorption study with14C-IR5878 was carried out in four different soils.The calculated Kocwere 283, 328, 550 and 249, for sandy loam, silt loam, silt loam and clay loam soils, respectively
