Carbon nanofibers were prepared by one-step carbonization of bacterial cellulose and used to detect Cd(II) and Pb(II). The detection limits are 0.38 μg·L−1 for Cd(II) and 0.33 μg·L−1 for Pb(II), respectively. The work was developed as a collaboration with Prof. Hu and Prod. Mamat (China). The results  are published in the journal of Microchimica Acta.

Abstract

The authors describe the preparation of carbon nanofibers (CNFs) with a three-dimensional network structure by one-step carbonization of bacterial cellulose at 800 °C. The 3D CNFs wrapped with Nafion polymer were cast on a glassy carbon electrode (GCE) which then enables sensitive detection of Cd(II) and Pb(II). Under optimized conditions and at typical stripping peaks of around −0.80 and −0.55 V (vs Ag/AgCl), the electrode exhibits high sensitivity and a wide analytical range of 2–100 μg·L−1 for both Cd(II) and Pb(II). The detection limits are 0.38 μg·L−1 for Cd(II) and 0.33 μg·L−1 for Pb(II), respectively. The modified GCE was successfully employed to the determination of trace amounts of Cd(II) and Pb(II) in both tap water and waste water.
