Centro de Documentacion de Fundación MAPFRE - A Comparative study of particle size dependency of IR and XRD methods for quartz analysis

Notes: Sumario: Quartz (SiO2) is considered a probable carcinogen. In order to enforce health and safety standards, techniques that can accurately determine the quartz content of materials are necessary. Currently, two techniques dominate quartz analysis - the infrared (IR) spectrophotometry method and the X-ray diffraction (XRD) method. Unfortunately, there are problems associated with these techniques, such as sample preparation and particle size effect. This study focuses on particle size effect on quartz determination by both IR and XRD. Seven size groups of pure quartz samples, with mean diameters from 1,5 to 20 microns, were usedRelated records: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 55, nº 7, July 1994 ; p. 605-609Materia / lugar / evento: Higiene industrial Contaminantes químicos Cuarzo Métodos de análisis Espectrometría Rayos infrarrojos Rayos X Otros autores: Li, Jianliang
