Comparing amorphous silica, short-range-ordered silicates and silicic acid species by FTIR

Ruth Ellerbrock et al.

Summary: There is increasing interest in the terrestrial silicon cycle due to its implications for ecosystem performance. The current analytical methods are limited, and Fourier-transform infrared spectroscopy (FTIR) analysis is suggested as a promising tool for differentiation. We conducted FTIR analyses on various silicon species and found that peak broadening and shifts in the Si-O-Si absorption band can indicate changes in internal order and incorporation of larger ions. Short-range ordered aluminosilicates (SROAS) can be distinguished from pure amorphous Si species using specific IR absorption bands.
