Quantitative Determination of Aluminum-substituted Goethite-hematite Mixtures by Mossbauer Spectroscopy


-Mixtures of synthetic Al-substituted goethite (a-Feo.814AloA86OOH) and hematite (a-Fel.658Alo.34203) (75, 50, 25, 3~ hematite by weight) were studied by M6ssbauer spectroscopy to evaluate the use of that technique for quantitative analysis. M6ssbauer spectra for these mixtures, obtained in the temperature range 12-130 K, were better fitted by a… (More)
