متن کاملInterstratifi ed kaolinite-smectite: Nature of the layers and mechanism of smectite kaolinization
This study aims to contribute to a better understanding of the nature and evolution mechanism of interstratifi ed clay minerals. We examined the <2 μm or <0.2 μm size fraction of interstratifi ed kaolinite-smectite (K-S) formed by hydrothermal and hydrogenic alteration of volcanogenic material from a Tortonian clay deposit (Almería, Spain), a weathered Eocene volcanic ash (Yucatan, Mexico), and...
متن کاملphenanthrene sorption onto kaolinite; heavy metals and organic matter effects
several factors effect on sorption of polycyclic aromatic hydrocarbons (pahs) in soil. co-existence of metals and organic matter of soil are among important affecting factors on sorptive behavior of pahs. this research investigated the effect of organic matter content and heavy metals (lead, nickel and zinc), on sorption of phenanthrene onto kaolinite. for this purpose, sorption of the organic ...

متن کاملPhysiologically Based Structure of Mean Residence Time
A mean residence time (MRT) is an important pharmacokinetic parameter. To the author's knowledge, however, a physiologically based structure of MRT (thereafter MRT structure) has not been published so far. Primarily this is because MRT structures cannot be identified by traditional pharmacokinetic methods used for the determination of MRT. Therefore, tools from the theory of linear dynamic syst...
