Popis:	Nanographite oxide was synthesized from thermally expanded graphite in an environmentally friendly electrochemical manner, and its adsorption properties were examined in a batch system. Three two-parameter isotherm models (Langmuir, Freundlich, and Dubinin–Radushkevich) were applied for the experimental data processing, and the adsorption kinetics was estimated according to pseudo-first and pseudo-second order simplified kinetic models. The acquired results revealed that obtaned nanographite oxide can be employed as an inexpensive and efficient adsorbent for removal of acidic dyes from aqueous solutions.
