Influence de la matière organique et de la teneur en eau du sol sur les phenomenes de sorption de l'aniline

Influence of organic material and soil moisture content on the adsorption of aniline Adsorption of aniline is directly related to the organic content of the soil and appears to depend mainly on the humic acid content. The competitive effect of soil water in the adsorption of aniline was examined. The influence of colloidal suspensions on adsorption was such that in natural surroundings only trace quantities of aniline were found in soil liquid. In every case, desorption was accompanied by a pronounced hysteresis effect, but salt solutions (CaCl₂) had the greatest ability to displace adsorbed aniline.
