英文摘要A novel graphitic carbon nitride (g-C3N4) nanosheet adsorbent with a large surface area, remarkable hydrophilicity and high adsorption capacity, was presented for the removal of cadmium ions (Cd2+) and methylene blue (MB) from aqueous solution. Adsorption measurements were conducted systematically to study the influences of the contact time, initial concentrations of Cd2+ and MB, temperature, and pH value. The maximum adsorption capacities of g-C3N4 towards Cd2+ and MB were 94.4 and 42.1 mg g(-1), respectively, at 318.5 K when the initial concentrations of Cd2+ and MB were 200 and 20 mg I-1, respectively. The adsorption kinetics fit a pseudo-second-order model. The high adsorption performance of the g-C3N4 adsorbent can be attributed to the multiple adsorption sites on g-C3N4, including the pi-pi conjugate interactions and electrostatic attractions with pollutants in water. In addition, it is significant to achieve high adsorption performance of g-C3N4 nanosheets by efficiently exposing the adsorption sites by adjusting the microstructure surface properties and dispersity in solution.
