摘要：

Al-substituted hydroxysulphate green rust (Al-GR{SO4}) were synthesised by the coprecipitation of Fe-II, Fe-III and Al-III cations. The Al- GR{SO4} crystals (similar to 50 nm) are significantly smaller than the hydroxysulphate green rust GR{SO4} crystals (similar to 500 nm). The Mossbauer spectrum of Al-GR{SO4} was adjusted with two ferrous doublets D-1 and D-3 and one ferric doublet D-2. Doublet D-3 is attributed to Fe-II ions that have Al-III ions as a first neighbour.
