外文摘要：Graphitic-C3N4 (g-C3N4) nanosheets, which prepared by a simple thermal and ultrasonic method, were used as a promising adsorbent for highly efficient scavenging of P(V), Cr(VI), Re(VII) from wastewater. The impacts of water chemistry like pH, foreign ions and ionic strength were investigated. The adsorption of P(V), Cr(VI), Re (VII) can reach 94.75, 108.91 and 143.31 mg/g. The adsorption kinetics and isotherm of P(V), Cr(VI), Re(VII) on g-C3N4 fitted well with pseudo-second-order equation and Langmuir adsorption model, respectively. The thermodynamic parameters indicated that the adsorption of P(V), Cr(VI), Re(VII) on g-C3N4 was a spontaneous endothermic process. Besides, the g-C(3)N(4)nanosheets exhibited a good recycling performance in the efficient scavenging of P(V), Cr(VI), Re(VII) from wastewater, while also showed high removal efficiency of mixed pollutants from real wastewater. According to these results, g-C3N4 can be a potential and promising adsorbent for the remediation of P(V), Cr(VI), Re(VII) from wastewater. (C) 2018 Elsevier B.V. All rights reserved.
