英文摘要Currently, the increasingly severe pollution of organic wastewater from dyes and antibiotics has become one of the major causes for the deterioration of the water environment. In this work, nanosheets-MnxOy anchored biochar (MnxOy@BEP) obtained from the marine polluting algae Enteromorpha was synthesized by a hydrothermal method, which exhibited extraordinary adsorption performance for tetracycline (TC) and methyl blue (MB). Nanosheets-MnxOy was grown in situ on the surface of biochar by pyrolysis of KMnO4, and the MnxOy@BEP composite had a micronano hierarchical structure, a larger specific surface area (208.735 m2 g-1) and more abundant active adsorption sites. Because of these characteristics, the MnxOy@BEP composite was endowed with excellent performance of organic pollutants in aqueous solution, which exhibited a high equilibrium adsorption capacity for TC (102.25 mg g-1) and MB (798.8 mg g-1), a rapid adsorption rate for MB (within 6 min) and selective adsorption properties at controllable pH. The experimental data of MB and TC was better fitted to the Langmuir isotherm model and pseudo-second-order kinetic model. Furthermore, the adsorption mechanism mainly involves electrostatic interactions, pi-pi interactions, hydrogen bonding, steric hindrance, etc. In addition, three cycles of adsorbent regeneration via 1.0 M NaOH solution displayed additional attractiveness. Therefore, the MnxOy @BEP composite material not only contributes to the management of Enteromorpha pollutants but can also be regarded as an extraordinary candidate for the removal of dye and antibiotic water.
