Mössbauer Study of the Attenuation of Iron in an Irrigated Greensand Lysimeter

Abstract: Abstract--Fe 57 Mfssbauer spectroscopy has been used to determine the nature of iron-containing minerals in Lower Greensand samples from an experimental lysimeter at Uffington, Oxfordshire, both before and after a three-year irrigation with a synthetic heavy metal leachate. Analysis of the spectra measured at 300 ~ 77 ~ and 4.2~ and at 4.2~ in an applied field of 45 kOe shows that iron is present in the uncontaminated sandstone in fine-grained goethite (a-FeOOH) and glauconite. In the irrigated samples iron is… Show more

“…A temperature dependence of the quadrupole splitting of the Fe 2+ doublets was observed between 20 and 300 K, quite similarly to that found in the work [8]. Neither magnetic component nor subspectra of tetrahedral Fe 3+ were identified in the Mössbauer spectra.…”

“…This glauconite has a higher iron content and also a large tetrahedral Fe 3+ component, which also confirms the hypothesis that an increasing extent of Fe 3+ tetrahedral substitution progressively directs iron substitution within the octahedral layer towards cis-OH sites. This assignment of the Fe 2+ resonances confirms those of McConchie et al (1979) and Ross and Longworth (1980) and negates those ofRolfet al (1977), Rozenson and Heller-Kallai (1979), Kotlicki et al (1981), and De Grave et al (1985).…”

“…The M6ssbauer spectra of illite and glauconite have also been reported by a number of workers (Rolf et al, 1977;Rozenson and Heller-Kallai, 1978;McConchie et al, 1979;Ross and Longworth, 1980;Kotlicki et al, 1981;De Grave et al, 1985). In general, these spectra show the presence of both Fe 2+ and Fe 3+ in the structure, and most spectra have been resolved into two Fe 3+ and two Fe 2+ doublets (e.g., De Grave et aL, 1985).…”

“…Ross and Longworth (1980) measured the spectrum at 4.2~ and in a 45 kG longitudinally applied magnetic field of a noncrystalline ferric hydroxide phase precipitated on a sandy clay. The spectral contribution of the gel was not well resolved from that of other Fe species present, but it appeared to be quite broadened, with a splitting of about 490 kOe.…”
