Easy-handling bamboo-like polypyrrole nanofibrous mats with high adsorption capacity for hexavalent chromium removal.

Development of highly efficient and easy-handling absorbents for heavy metals removal is desirable for the remediation of our existing aquatic system. Herein, we demonstrated the novel bamboo-like polypyrrole nanofibrous mats for the removal of highly toxic hexavalent chromium (Cr(VI)) from aqueous solution. To achieve this target, the VO nanofibrous templates were prepared via non-emulsion electrospinning technique and calcination, followed by in-situ polymerization of pyrrole.
