Boron Release from Weathering of Illites, Serpentine, Shales,and Illitic/Palygorskitic Soils.
Evidence for boron in both trigonal and tetrahedral coordination has been found in B magic-angle-spinning (MAS) nuclear magnetic resonance (NMR) spectra ofnatural, inclusion-free speci-mens of alumin...
This very large overview of the role of boron in mineralogy, petrology and geochemistry divides itself with minimal over- lap and clutter into three parts: crystal chemistry°(TM)includin thermochem...
Piston-cylinder experiments with C-H-O fluids in equilibrium with graphite as redox sensor were performed at 900!a and 10 kbar. With this technique, it is possible to inves- tigate the hydrogen perm...
Sorption of Boron by Hydrous Al-Oxide     Boron  Hydrous Al-oxide  pH       2011/12/1
Abstract: Boron sorption by hydrous Al-oxide was studied as a function of concentration, pH, temperature and in the presence of oxalate and phosphate. For comparison sorption of B was also measured wi...
Boron adsorption at constant ionic strength [0.09 ?0.01 moles/liter of KClO4 or Ca(ClO4)2] on 0.2? 祄 clay fraction of pretreated kaolinite was modeled using both phenomenological equations and surface...
An assemblage of clay minerals, Na-zeolites, Fe- and Sb-sulfides, and borates occurs in cavities in the basalt flow that underlies the main borax ore body exposed by the U.S. Borax open pit at Boron, ...
Boron adsorption on 2-0.2-祄 size fractions of kaolinite at 25??2癈 at pH values between 6.0 and 10.5 was studied. The kaolinite sample was pretreated to remove any surface oxide and hydroxide coatings....
The effects of exchangeable Na and Ca and the ionic strength of NaCl and CaCl2 solutions on the boron adsorption by the Na and Ca forms of montmorillonite and illite at pH 9 were studied. The boron ad...
Boron adsorption by Ca forms of montmorillonite, illite, and kaolinite was determined as a function of pH and boron concentration in solution. Data from batch experiments were compared with results co...
Boron Fixation by Illites     Boron Fixation  Illites       2012/2/21
The mechanism of boron uptake by clays, especially illitic clays, and the factors which control such uptake have long been debated issues. In an attempt to answer some of the questions of the controve...
