Quantitative photoacoustic spectrometry

Characterisation of the grafting of (3-aminoethyl)aminopropyltrimethoxy silane on precipitated silica

“…These two copper(II) complexes immobilised on silica gel can be identified by UV-visible spectroscopy because of the difference in their maximum absorption wavelength. 26 The deconvolution of the spectra (Fig. 3) provides the relative amount of each complex in the sample (Table 1).…”
