A sequential extraction procedure developed by the European Community Bureau of Reference (BCR) was applied to eight sediment geochemical reference materials provided by the Geological Survey of Japa...
Abstract: As a consequence of treatments with glycine solutions, glycine molecules enter the interlayer of both Ca- and Cd-rich montmorillonite. Measurements of d value suggest that at low glycine con...
This study compared surface characteristics and dissolution behavior of well-crystallized (KGa-1b) and poorly crystallized (KGa-2) kaolinite standards. Atomic force microscopy (AFM) revealed that pa...
X-ray absorption fine structure spectroscopy (XAFS) was used to determine arsenic (As) oxidation state, local coordination (to a radius of ┆7Aⅹaround As), and the relative proportion of different As s...
Abstract: Surface adsorption mechanisms of dissolved inorganic carbon species on soil minerals are not well understood. Traditional infrared (IR) study of adsorbed species of inorganic carbon using ai...
In situ, high-temperature Raman spectroscopy of Na,O.9SiO, glasses and melts with and without 2 mol% P,05 has been conducted to 1491 K (near the liquidus temperature). In the temperature range from 29...
Diffuse reflectance spectra of kaolins have been recorded in samples from different environments. They show the systematic presence of Fe-oxides, even in bleached kaolins, with no contribution from th...
