摘      要：The recovery of scattered metal ions such as perrhenate(Re(VII))from industrial effluents has enormous economic benefits and promotes resource ***-metal/biochar hybrid biosorbents are attractive for recovery but are limited by their insufficient stability and low selectivity in harsh ***,a superstable biochar-based biosorbent composed of ZnO nanoparticles with remarkable superhydrophobic features is fabricated,and its adsorption/desorption capabilities toward Re(VII)in strongly acidic aqueous solutions are *** ZnO nanoparticle/biochar hybrid composite(ZBC)exhibits strong acid resistance and high chemical stability,which are attributable to strong C-O-Zn interactions between the biochar and ZnO *** to the advantages of its hydrolytic stability,superhydrophobicity,and abundance of Zn-O sites,the ZBC proves suitable for the effective and selective separation of Re(VII)from single,binary and multiple ion systems(pH=1),with a maximum sorption capacity of 29.41 mg/*** importantly,this material also shows good recyclability and reusability,with high adsorption efficiency after six adsorption-desorption *** findings in this work demonstrate that a metal/biochar hybrid composite is a promising sorbent for Re(VII)separation.
