Abstract
A carbon electrode having a functional moiety that forms a charge-transfer complex with a nitro-containing compound covalently attached to a surface of the electrode, and a process of preparing such an electrode are provided. Also provided are sensing systems integrating the carbon electrode and methods utilizing same for electrochemical detection of nitro-containing compounds.
Claims23
An electrochemical cell comprising a sensing electrode, said sensing electrode being a working electrode and comprising a carbon electrode and a functional moiety covalently attached to a surface of said electrode, said functional moiety comprising an electron donating moiety and forms a charge-transfer complex with a nitro-containing compound,
- the electrochemical cell being such that upon contacting said nitro-containing compound with said sensing electrode and applying potential to said sensing electrode, a change in an electrochemical parameter as a result of electrochemical reduction of one or more nitro groups of said nitro-containing compound is effected.
A process of preparing a sensing electrode which comprises comprising a carbon electrode and a functional moiety covalently attached to a surface of said electrode, said functional moiety comprising an electron donating moiety and forms a charge-transfer complex with a nitro-containing compound, the process comprising:
- coupling to a carbon electrode featuring a plurality of a first reactive group on at least a portion of its surface, a compound featuring said functional moiety and a second reactive group that forms a covalent bond with said first reactive group,
- thereby preparing the electrode.
