Rhenium sorption by fibrous chitosan-carbon materials

We studied equilibrium and kinetic characteristics of rhenium sorption by Busofit-based fibrous carbon materials (FCMs) treated electrochemically with recovery potentials varying from −900 to +600 mV from aqueous solutions in the presence of natural biopolymer chitosan. Materials obtained in the ano...

Description
Summary:We studied equilibrium and kinetic characteristics of rhenium sorption by Busofit-based fibrous carbon materials (FCMs) treated electrochemically with recovery potentials varying from −900 to +600 mV from aqueous solutions in the presence of natural biopolymer chitosan. Materials obtained in the anodic potential region and at the open-circuit potential have the best capacity characteristics. The highest rhenium capacity is observed for the material prepared at the recovery potential +600 mV. The relevant sorption isotherm is described by the Langmuir equation with the constant 73.0 ± 8.1 mL/mg; the half-conversion time is 3 min.
