Abstract

⁵⁷Fe Mössbauer effect spectroscopy studies were conducted on native crocidolite and on a sample which had been detoxified by means of a chemical treatment with ferric salts. This allows for a comparison between the crystal chemistry of the untreated and treated samples. Significant chemical changes in the treated sample have been inferred from the Fe site-population analysis after conducting a temperature-dependent study of both samples in the range 300 K down to 90 K. These results, together with the results from complementary Electron Spin Resonance (ESR) studies, may help to elucidate the mechanism of toxicity in these asbetiforms.
