Sensing Performance

Poly(3,4-ethylenedioxy-thiophene):polystyrenesulfonic acid (PEDOT:PSS), a commercially available aqueous conducting polymer, as the electrode modified material for the development of sensing and biosensing devices has not been widely reported due to its swelling and disintegration in aqueous solution. For this purpose, A poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) modified electrode was facilely fabricated for the electrochemical detection of catechol. 1-butyl-3-methylimidazolium hexafluorophosphate, one of hydrophobic ionic liquids, was used for secondary dopant and enhancer to improve the water-resistance and the electrochemical properties of PEDOT:PSS polymer film. The as-prepared PEDOT:PSS modified electrode exhibited the pronounced water-stability and good sensing performance, which make PEDOT:PSS as an interesting candidate of the electrode modified material for application in sensing and biosensing devices in the near future.

The Stability

This work shows the viability of conductometric titration of Ag+ in aqueous medium, with thioacetamide. First, the stability of thioacetamide in aqueous solution was tested. Analysis of during 5 weeks weeks did not show any concentration change in a thioacetamide solution.To get betteraccuracy in the results o four analysis, the titrating and titrated solutions were used in different concentrations. The lowest relative error (0.12%) was found in the titration of a 0.01N solution of silver nitrate with a 0.1 N solution of thioacetamide.
