...S. Naamen; N. Jâafar; H. Ben Rhaiem; A. Ben Haj Amara; A. Plançon; F. MulLer Abstract An homogenous intercalated compound of dioctahedral 1:1 clay mineral with cesium chloride was prepared by immersing an homogeneous 8.4 Å hydrated nacrite in a CsCl-saturated solution. The nacrite/CsCl complex...

... drastically on zeolite. The cesium desorption from the layered minerals was promoted by the addition of ammonium ions, namely trioctylmethylammonium chloride and zephiramine. These ammonium ions desorb cesium from the interlayers of the minerals without destroying the mineral structure. The cesium desorption...

... amounts of lithium, rubidium, and cesium, and the major anions to be chloride and sulfate in an aqueous solution. A quantative determination of the above ions was made.In the minerals from Portales, New Mexico, a correlation appears to exist between the sodium to potassium ratio and the temperature...

... preparation. Cesium and strontium were supplied as cesium chloride and strontium chloride by Merck, Germany. Natural clinoptilolite was collected from the Aftar deposit located northwest of Semnan, Iran. In order to remove soluble salts, the zeolite was dispersed in distilled water and stirred for 12 h at 343...

... upward into the column at a Darcy velocity of 4.5 cm h −1 using a syringe pump. An aqueous solution containing tetrachloroethene and iodobenzene at solubility concentrations based on the composition of the organic liquid (assuming Raoult's Law applicability), as well as the cesium chloride salt...

...Laura A. Wendling; James B. Harsh; Carl D. Palmer; Melinda A. Hamilton; Markus Flury Abstract Cesium uptake by plants depends on adsorption/desorption reactions in the soil, as well as root uptake processes controlled by the plant. In this study, sorption and desorption of Cs + on reference illite...

... Society (Chantilly, USA). Ammonium pertechnetate was obtained from LEA-CERCA (France). All other reagents (sodium hydroxide, chloride, nitrate and sulfate) were obtained from VWR international (USA). In all instances, aerobic batch experiments were carried out in sealed 50 ml polypropylene Oakridge...

...-00051 (study of oxides and chlorides of chalcophile metals) from the Russian Foundation for Basic Research. Cesium minerals. Cesium is the only lithophile rare metal whose minerals and their geochemistry have a significant relationship with oxidizing-type fumaroles. For example, avogadrite (K,Cs...

...Alexander F. REDKIN; John J. HEMLEY Abstract Experimental studies on replacement of Na by Cs and Sr in analcime-albite bearing buffered assemblages were carried out at 250–300°C and P sat = 39.7-85.8 bars in pure water and in chloride solution. This investigation shows that such ion exchange of Na...

... the continental margins of the ocean basins, inland seas, continental brine lakes, and salt pans. Trace minerals, such as bromine, cesium, and rubidium, are of special interest in saline studies, because they furnish much information on the genetic character of the salts. Argon, commonly found within salt...

... substitution for Si produced a local charge imbalance. Kaolinite, a 1:1 clay mineral, adsorbs very little cesium on its external surfaces. Elevated temperature and pressure, similar to those that would occur in an underground repository, do not affect the amount of Cs + adsorbed by montmorillonite. Cesium-133...

... to which cesium chloride had been added. This demonstrates that Cs-PBT is more stable than Na-PBT (since simple ion exchange reaction is only possible if one compound is more stable as the other), and that the phase produced by this different method is not identical with the β-Cs-PBT, which can also...
