...J. E. F. C. GARDOLINSKI; G. LAGALY; M. CZANK Abstract Kaolinite and synthetic γ-Al(OH) 3 (gibbsite or hydrargillite) were reacted with phenylphosphonic, phenylphosphinic and 2-nitrophenol-4-arsonic acids. The products were studied by powder X-ray diffraction, transmission electron microscopy...

... reported was the indirect synthesis of 1,2- and 1,3-propanediol and 1,2- and 1,3-butanediol-kaolinite by transesterification of the methanol derivative ( Itagaki & Kuroda, 2003 ; Murakami et al. , 2004 ). The formerly described derivative of kaolinite with phenylphosphonic acid ( Guimarães et al...

...Thaís R. Macedo; Giovanni C. Petrucelli; Claudio Airoldi Abstract Some n-alkyldiamines with the general formulae H 2 N(CH 2 ) n NH 2 ( n = 2–5) were intercalated into the layered silicic acid magadiite, from aqueous solution, causing an increase in the original interlayer distance of 1172 pm...

... constant, and n is the Freundlich exponent ( Sips, 1948 ). Firstly, the effect of pH on adsorption for all clay samples was evaluated by varying this parameter over the range 1.0–5.0, with addition of 0.10 mol dm −3 of nitric acid or sodium hydroxide. The pH of the solutions was measured using a pH/Ion...

... nitric-acid digestion bottles. The sample was then digested with 7.0 cm 3 of concentrated nitric and hydrochloric acids (ratio of 1:3 by volume), with an identical volume of hydrofluoric acid (1.0 mol dm −3 at room temperature) over 5 days. The bentonite samples were cooled in an ice bath and 25.0 cm 3...
