HYPOTHESIS The environmental mobility and bioavailability of Picloram (PCM) are determined by the amine and carboxylate chemical groups interaction with the soils mineral phases. Clay particles, such as montmorillonite (Mt), and the pH value of the media could play an important role in adsorption processes. Thus, the study of the role of soil components(More)
The Na+-humate sol is studied as a surface active substance (surfactant) capable of lowering the surface tension of water, and of spreading on the water surface with observable velocity to form a thin film. Based on these properties, it is concluded that sol should contain molecules of intermediate molecular weight as well as their associates (micelles)(More)
Experimentos do fluxo da água usando um meio poroso não saturado compoto por diferentes sistemas de aalumina molhada não-saturada indicam que a carga superficial da partícula diminuiu com o aumento da água movimentada. O movimento máximo de água ocorreu quando a carga superficial era zero. O movimento da água foi afetado pela espessura da dupla camada(More)
