    Notizen: Abstract Using laser microproble mass analysis (LAMMA), it is possible to characterize the inorganic composition of clays and to study adsorption phenomena. Natural sepiolite, (Na-sepiolite), montmorillonite and saponite samples from Anatolia (Turkey) have been investigated. All the clays gave different fingerprint mass spectra which allowed a quick estimation of the relative amounts of exchangeable cations as well as the trace contaminants and the homogeneity of their distribution. The adsorption behaviour of these clays for pyridine was also studied and it appeared that pyridine molecules penetrated the inner layers, as well as being adsorbed on the external surface.

    Infrared spectral investigations of adsorption and oxidation of N,N-dimethylaniline by sepiolite, loughlinite and diatomite (1987)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 5 (1987), S. 259-262

    Notizen: Abstract The adsorption behaviour of sepiolite, loughlinite (Nasepiolite) and diatomite for N,N-dimethylaniline (DMA) and its catalytically formed oxidation products are studied using IR spectroscopy. It is found that sepiolite and loughlinite adsorb DMA and then react with it more easily than diatomite. The adsorption capacity sequence of DMA for the minerals studied is sepiolite 〉 loughlinite 〉 diatomite.
