Firstly, taking l-tyrosine as the reductant, one novel three-dimensional graphene aerogel with excellent adsorption capacity to appointed organic solvents was fabricated and characterized by Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, thermogravimetric analysis, etc. This graphene aerogel adsorbent with good mechanical property and low density possessed a good adsorption and selectivity to some appointed solvents, such as CHCl3, CHCl2, etc., and the adsorption amount to CH2Cl2 even could reach 87.6 g g−1. Hence, the prepared l-tyrosine reduced graphene aerogel with facility fabrication and favorable selective adsorption, as an effective, environmentally friendly, adsorption material could be applied in environmental remediation for special organic solvents adsorption, potentially.
