General description

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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Click here for more information.
