Adsorption et désorption de la pyrazone par quelques colloïdes organiques et minréaux

Abstract: Résumé: On a éludié l'adsorption et la désorption de la pyrazone sur des colloïdes organiques et minéraux et sur des résines échangeuses d'ions saturées par les ions H+, Na+, K+, Ca++ et Mg++. Pour ce qui concerne les adsorbants‐H, on a trouvé l'ordre d'adsorption suivant: Amberlite‐H> Dowex‐H > humus‐H> montmorillonite‐Al,H > illite‐Al,H > kaolinite‐ Al,H. Cette adsorption, qui semble etre due à des liaisons physiques et non à des mécanismes de protonation, est plus grande que celle trouvée avec des systèmes‐… Show more

“…Flu chloralin, profluralin, and trifluralin are three members of this class of herbicides that have been shown to be relatively similar in persistence (19) and phytotoxicity (5,9). Brewer et al (3) recently reported injury and yield reductions of rice from these herbicides if their soil concentrations exceeded 0.2 ppm. Their persistence in soybean-rice rotations, there fore, becomes important.…”
