Infrared and Raman spectra of magnesium ammonium phosphate hexahydrate (struvite) and its isomorphous analogues. I. Spectra of protiated and partially deuterated magnesium potassium phosphate hexahydrate

Influence of tempereature on Struvite precipitation by CO2‐deagassing method

“…The identification of struvite precipitated as a single phase was confirmed by infrared analysis (figure not shown). The experimental data are in full agreement with the recent publications [16][17][18] relative to infrared analysis of struvite, dittmarite, and newberite. Vibrations localized at 1030 and 571 cm −1 are characteristic of the mono-phosphate group.…”

Geochemical and mineralogical investigation of domestic archaeological soil features at the Tiel-Passewaaij site, The Netherlands

“…Additional information from the FT-IR spectra is obtained from the absence of some specific phosphate signals. It was hence possible to exclude the presence of (hydroxy) apatite, struvite and vivianite which have characteristic vibrations at about 1130 cm − 1 (Antonov et al, 1996), 450 cm − 1 and 428 cm − 1 (Stefov et al, 2004), and about 1300 cm − 1 and 1500 cm − 1 respectively (McLean et al, 1991).…”

Thermal, spectral and microscopic studies of water-rich hydrate of the type Mg2KH(PO4)2·15H2O. Thermal transformations

“…Similar to the struvite type compounds [18][19][20], the broad spectral features in the 3700-2000 cm −1 region of the IR spectra of Mg 2 KH(PO 4 ) 2 ·15H 2 O is reminiscent of an AB double band that is characteristic for systems with strong hydrogen bonds [21]. A part of the complex band below 3000 cm −1 can be assigned to the A component whereas the band centered at 2390 cm −1 to the B component of the AB doublet (Fig.…”
