Creator:: Hiltner, Phyllis Anne, 1941-
Abstract:: Adsorption on a series of primary n-alkylammonium bentonites was studied by simultaneous gravimetric determination of the adsorption isotherm and X-ray diffraction measurement of the c-spacing. All adsorbates gave typical Type II isotherms. BET plots were linear in the region P/P[subscript o] = 0.10 - 0.35 and v[subscript m] values were...

Creator:: Carstea, Dumitru Dumitru
Abstract:: The influence of pH (titration method) and of salt concentration and drying (drying method) upon the formation of synthetic AI, Fe, and Mg interlayers in montmorillonite and vermiculite was investigated. Interlayer formation was evaluated by X-ray diffraction measurements of basal spacings using a natural chlorite for comparison. The titration method...

Creator:: Carstea, Dumitru Dumitru
Abstract:: The effects of pH and time on the formation of hydroxy-Al, Fe, and Mg interlayer were compared for montmorillonite and vermiculite. The stability of interlayers was evaluated by sequentially increasing the severity of dissolution treatments and by subjecting the inter-layers to an HC1 treatment. The interlayer formation and stability were...

Creator:: Carter, Loren Sheldon
Abstract:: Water and methanol adsorption isotherms at 25° and 37° C. were determined on a series of organo-bentonite clays. The clays differed in the length of the carbon chain attached to the amine adsorbed in the cation exchange position. The amines used had carbon chains of 4, 6, 8, 10, 12,...

Creator:: St. Clair, Akos Dominic
Abstract:: Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...

Creator:: Inskeep, William Parks
Abstract:: The formation of solution and solid complexes with heavy metals will partially determine their mobility and plant availability in soil systems. Experiments were initiated to determine the effect of pH, adsorbent and initial metal concentrations, and the presence of water soluble ligands on the adsorption of Cd and Cu by...
