An empirical relationship was established between total water content and the negative peak height normalized by the baseline extrapolated from the neighboring region (ΔR/R baseline); for example, H2O wt.% = 49.76 ×ΔR/R baseline − 0.08 for basaltic composition. The regression error ...
The structure of water (4% D2O in H2O, v/v) solubilized by the reverse aggregates of cetyltrimethylammonium bromide in a chloroform/n-dodecane mixture (6:4, v/v) was probed by FT-IR. The vOD band of solubilized HOD was recorded as a function of the [water]/[surfactant]molar ratio,...
DSCFT-IRStruvite (MgNH4PO4·6H2O; MAP) can be recovered from animal and human wastes for use as fertilizer. This encourages the sustainable use of phosphorus (P), closing the human P cycle. The toxic metalloid chromium (Cr) is a common component of wastes, and can substitute for P in...
We obtained new infrared data for CO2, N2O and H2O sorbed in PMMA film. An additional shoulder at 3420 cm−1 besides two peaks at 3630 and 3550 cm−1 was observed in the IR spectra of the water species sorbed in PMMA. Species of N2O in PMMA has a peak at 2223 cm−1, which ...
