In situ preparation of mycelium/bayberry tannin for the removal of strontium from aqueous solution

A new sustainable filamentous fungi-based process is reported to synthesize mycelium/bayberry tannin (BT) hybrid materials. The hybrid materials are produced with fungi growing in solution, where the cell wall interacted with BT by hydrogen-bond from the phenolic hydroxyl and amino in protein. In the adsorption experiment, This hybrid biologic material show excellent performances for strontium ions adsorption and experimental data obey a pseudo second-order model of the chemical adsorption process. This study reported a new method for the producing of bio-based materials, which had the potential applications in waste water treatment. (author)
