Abstract

This paper describes the fabrication of a composite material consisting of Cladophora cellulose and polyaniline (PANI). Cellulose extracted from environmentally polluting green algae Cladophora rupestris was used as a matrix and conducting polyaniline coating was applied on its surface. The characterization of the composite revealed the presence of a nano-layer of PANI coating on the cellulose fibers, thus preserving the high surface area of the cellulose. The cellulose/PANI composite was used effectively as a reducing agent in the remediation of toxic hexavalent chromium. The efficiency of the reduction activity of metals can be attributed to the high surface area of the cellulose/PANI composite. This study provides alternative ways to solve an environmental issue and maximize the use readily available resources.
