Abstract
, dose 0.1 g, pH = 7.0, adsorption temperature 55°C, adsorption time 2 h. The adsorption kinetics and thermodynamics analysis indicated that the adsorption of two dyes onto Pst@GO was endothermic reaction, while electrostatic attraction and hydrogen bonding are the main driving forces for the adsorption reaction.Polystyrene @ graphene oxide layered composite microspheres (Pst@GO) were prepared by Pickering emulsion method to remove dye pollutants in water. The preparation process of Pst@GO is as follows:Figure 1 Schematic fabrication process of Pst@GO.
