Investigation of the Electrochemical Behaviour of MWCNTs in the detection of Cr(VI)
Garry, Lynn M. and Alcock, Bernadette E. and Breslin, Carmel B. (2011) Investigation of the Electrochemical Behaviour of MWCNTs in the detection of Cr(VI). ECS Transactions, 41 (27). pp. 1-7. ISSN 1938-5862 AbstractThe electrochemical behaviour of a glassy carbon (GC) electrode
modified with MWCNTs was investigated and characterised using
K3[Fe(CN)6] as a probe. An increase in the electroactive surface
area and the rate of electron transfer was observed on sonication of
the MWCNTs prior to casting at the GC electrode. The modified
electrode was also used in the detection of Cr(VI) in both pH 5.0
and pH 2.0 aqueous solutions. Better detection limits were
obtained in the acidic solution. | Additional Information: | © The Electrochemical Society, Inc. [year]. All rights reserved.
