Practical determination of allophane and synthetic alumina and iron oxide gels by X-ray diffraction

Abstract X-ray diffraction methods are effective and practical for the quantitative analysis of the often forgotten amorphous material phase in sediments. The method reported is simple, employing normal oriented samples, and quartz or fluorite as a diluent. However, special care must be taken to prepare the samples properly, to ensure optimum conditions for diffraction, and to measure accurately the scattering bands.
