摘要：Chlorine-functionalized reduced graphene oxide (ClRGO) reacted with ammonia, and subsequently ammonia-modified reduced graphene oxide was formed. The sample was characterized with various techniques. The nitrogen content of the product is high (17.0 atomic %), the binding energy of C–N is at 285.1 eV, which means that the bond of C and Cl reacts with ammonia. The interlayer distance is larger than that of reduced graphene oxide. The product has a higher adsorption capacity (170.1 mg/g) for methylene blue than activated carbon (46.7 mg/g) and reduced graphene oxide (77.0 mg/g). The adsorption data were dealt with three favorite kinetic models and helpful models of adsorption isotherm. The adsorption data in this experiment are consistent with the quasi second order kinetics and the Langmuir model. ? 2023, The Authors. All rights reserved.
