An account is given of the interactions between clay minerals and organic polymers with particular reference to their applications in agriculture, foundation engineering and industry.

Abstract Background Phytotoxins of various classes and origin are often found in their cationic form the soil environment thus, overall behavior may be strongly affected by all geosorbents presenting cation exchange capacity (CEC). In addition to organic carbon (SOC), clays exhibit great potential as sorbents for chemicals. Therefore, 52 compounds major phytotoxin alkaloids, terpenoids steroids...

Clay-size minerals play important roles in terrestrial biogeochemistry and atmospheric physics, but their data have been only partially compiled at global scale. We present a global dataset of clay-size minerals in the topsoil and subsoil at different spatial resolutions. The data of soil clay and its mineralogical composition were gathered through a literature survey and aggregated by soil ord...

Define a mixture with volume V containing a certain amount of clay (Vc) and sand (Vs), i.e. V = Vc + Vs. The intrinsic porosity of the clay is φc, defined as the ratio of pore volume in the clay V c p to the volume of clay, i.e. φc = V c p /Vc, and the intrinsic porosity of sand is φs = V s p /Vs. The surface areas of the pores in the clay and in the sand are noted S p and S s p respectively. S...
