ChemInform Abstract: HYDROTHERMAL SYNTHESIS AND MOESSBAUER STUDIES OF FERROUS PHOSPHATES OF THE HOMOLOGOUS SERIES FE32+(PO4)2(H2O)N

Abstract

Durch progressive Dehydratation unter kontrollierten hydrothermalen Bedingungen werden ausgehend von Vivianit Fe3(PO4)2°C 8 H2O die bekannten hydratisierten Spezies Ludlamit (n=4) und Phosphoferrit (n=3) sowie die 2 wasserfreien Minerale Sarkopsid und Graftonit neben 3 neuen Spezies mit n = 4, n = 2 und n = 1 synthetisiert.

Biomineralization of lepidocrocite and goethite by nitrate-reducing Fe(II)-oxidizing bacteria: Effect of pH, bicarbonate, phosphate, and humic acids

“…Analysis temperature was 4.5 K for the 0, 0.2, and 1.0 mM total phosphate suspensions and 77 K for the 3.0 mM total phosphate suspension. Additional information for solution conditions is in Table 1 and Mö ssbauer parameters are reported in Table 2. vivianite (Mattievich and Danon, 1977). Note that this spectrum was collected at 77 K, as opposed to 4.5 K for the others in Fig.…”
