The sorption behavior of CS ion on clay minerals and zeolite in radioactive waste management: sorption kinetics and thermodynamics
In this work, Cs ion sorption on some clays and zeolite were investigated. Cs was used as a tracer. Activities were measured with a NaI crystal gamma counter. The particle size distribution was determined by a laser sizer. Surface area of the particles were determined by BET (Brunauer, Emmett and Teller method). Structure analysis was made by using X-ray diffraction. The chemical compositions o...
متن کاملSorption and Desorption of Pesticides by Clay Minerals and Humic Acid-Clay Complexes
small amounts of water to soil reduced the sorption of organic compounds relative to the sorption by the In soils, organic matter and minerals are often associated such that dehydrated soil in hexane, and that organic vapor adit is unclear how the presence of the former component influences sorption by soil was significantly depressed by increasing the sorptive properties of the latter one. In ...
متن کاملClay Minerals and Catalysis
More than half a century ago, Irish physicist John Desmond Bernal and Swiss geochemist Victor M. Goldschmidt independently proposed that clay minerals may have played an important role in prebiotic synthesis (Bernal 1949; Goldschmidt 1952). I concur that mineral catalysis must have had a central role in prebiotic synthesis because most uncatalyzed reactions start from simple precursors like hyd...
متن کاملClay Minerals: Adsorbophysical Properties
The structure and features of surfaces of clay minerals (kaolin, montmorillonite, etc) have an important scientific and practical value. On the surface the interrelation of processes at electronic, atomic and molecular levels is realized. Availability of mineral surface to external influences opens wide scientific and technical opportunities of use of the surface phenomena, so the research of c...
متن کاملCompetitive sorption between glyphosate and inorganic phosphate on clay minerals and low organic matter soils
Inorganic phosphate may influence the adsorption of glyphosate to soil surface sites. It has been postulated that glyphosate sorption is dominated by the phosphoric acid moiety, therefore, inorganic phosphate could compete with glyphosate for surface sorption sites. We examine sorption of glyphosate in low organic carbon systems where clay minerals dominate the available adsorption sites using ...
