TL;DR: In this paper, the authors used a batch experiment to determine the sorption characteristics of lead, zinc, copper and cadmium in the soil horizons of the Stara Loza water well field area of the Zagreb aquifer.
Abstract: The subject of this study is the Fluvisol profile, developed in the Stara Loza water wellfield area of the Zagreb aquifer. The main objectives of the investigation were: 1) to determine the sorption characteristics of lead, zinc, copper and cadmium using a batch experiment and 2) to build isotherms of potentially toxic metals (PTMs) in soil horizons of Fluvisol. The soil texture is silt loam of a light yellow colour, and granular structure. The pH values of the soil vary from 7.97 to 8.38. Cation exchange capacity (CEC) has higher values in the first three horizons. Based on the results of the experiment, linear sorption isotherms were created for all the soil horizons. Freundlich distribution coefficients are determined from sorption isotherms, and the sequence is Pb > Cu > Cd > Zn. The comparison of sorption isotherms has determined that lead has the best sorption in the soil. Sorption of potentially toxic metals decreases with depth.

TL;DR: In this article, a linear relationship exists between soluble sodium fraction and dilution, defined as the fraction of soluble sodium and the total extractable sodium, which can be used to recalculate soluble sodium at low soil: water ratios once the parameters of the relationship were determined.

TL;DR: In this article, the authors present silicates belonging to the sepiolite and palygorskite group of silicates, discussing their crystal structures, lattice parameters, nuclear gamma resonance (NGR), nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) data, electrical properties and dielectric behavior, and optical properties.
Abstract: This document is part of Subvolume I5β ‘Phyllosilicates – Part β’ of Volume 27 ‘Magnetic properties of non-metallic inorganic compounds based on transition elements‘ of Landolt-Bornstein - Group III ‘Condensed Matter’. It presents silicates belonging to the sepiolite and palygorskite group of silicates, discussing their crystal structures, lattice parameters, nuclear gamma resonance (NGR), nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) data, electrical properties and dielectric behavior, and optical properties.

TL;DR: Anomalous concentrations of talc have been found in residual soil associated with buried and blind talc bodies in southwestern Montana as mentioned in this paper, where the authors used X-ray diffraction analysis to identify 50% or more of the acid insoluble residue obtained from the marble.
