Ivanov AN, Lukachova LV, Evtugyn GA, Karyakina EE, Kiseleva SG, Budnikov HC, Orlov AV, Karpacheva GP, Karyakin AA: Polyaniline-modified cholinesterase sensor for pesticide determination. Bioelectrochemistry. 2002 Jan;55(1-2):75-7. Cholinesterase sensors based on glassy carbon and planar epoxy graphite electrodes modified with processed polyaniline have been developed and examined for pesticide detection. The modification of electrode surface with polyaniline provides high operational stability and sensitivity towards the pesticides investigated. The detection limits found (coumaphos, 0.002, trichlorfon, 0.04, aldicarb, 0.03, methiocarb, 0.08 mg l (-1)) make it possible to detect the pollutants in the waters on the level of limited threshold levels without sample preconcentration. |
