Elemental Analysis

The number of free amino groups measured with a quantitative Kaiser test: 0.1 mmol NH₂/g.

Amount of NH₂ groups:

In order to estimate the amount of NH₂ groups in rGO-NH₂ a reaction with tetrabromophthalic anhydride performed and the Br amount was quantified by X-ray fluorescence spectroscopy and by the Schöniger flask test. The value obtained corresponds to 0.23 mmol/g and 0.21 mmol/g respectively.
