Graphene nanosheets decorated with tunable magnetic nanoparticles and their efficiency of wastewater treatment
Source abstract
Abstract
Abstract Magnetic graphene–Fe 3 O 4 nanocomposites (G/Fe 3 O 4 ) were fabricated by a facile and fast one-pot method and used as adsorbent to remove dye for wastewater using Rhodamine B as the adsorbate. Samples with different weight ratios of graphene oxide (GO) to Fe 3 O 4 were prepared. The transmission electron microscopy results exhibit that the sizes of Fe 3 O 4 nanocrystals decrease with the increasing of weight ratio of GO to Fe 3 O 4 . The magnetic characterization demonstrates that the saturation magnetization of nanocomposites decreases with the decreasing sizes of Fe 3 O 4 nanocrystals. The investigation of adsorption kinetics and isotherm indicates the adsorption process can be described by Langmuir model and nanocomposites with the smaller sizes of Fe 3 O 4 nanoparticles show better adsorption ability. Furthermore, the adsorbents could be recovered conveniently by magnetic separation and recyclable used after desorption process, and the decline in efficiencies of all samples is not more than 1.5% after five cycling runs.
