M6ssbauer spectra of fresh samples did not show any magnetic components. After two years aging, the solids presented crystalline fractions. Hematite formation was inhibited as acetate content increased in solids. For an acetate/ iron molar ratio equal to 0.63 goethite was formed instead of hematite. X-ray diffraction confirmed these results. This work shows that synthetic samples can be used for elucidating the "anti-bematitic" effect of organic matter already detected in soils.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-09-16T18:25:57Z No. of bitstreams: 1 333333333333333.pdf: 396898 bytes, checksum: 1d099f63c9e6b1a59ba369ba833cdb51 (MD5)Made available in DSpace on 2013-09-16T18:25:58Z (GMT).
