Phospholipids improve selectivity and sensitivity of carbon electrodes: Determination of pesticide Paraquat
Original language description
Cyclic voltammetry and AC impedance spectroscopy were used for the investigation of properties and permeability of asolectin phospholipid layer and its influence on the voltammetric response of carbon electrodes. Permeability of the layer was tested using two electrochemically active compounds - paraquat as an example of lipophilic pesticide and copper sulphate as an example of hydrophilic substance. The phospholipid layer has suppressed the current response of copper ions effectively even in their large excess to paraquat. By contrast, the current response of lipophilic substance paraquat was almost unaffected by the phospholipid layer. As a result, the slope of calibration straightline for the copper ions was 14-times lower at the modified electrodethan at bare electrode. On the contrary, the slope of calibration curve for paraquat was almost the same at modified electrode compared to bare electrode. Unmodified (CPE) and phospholipid modified (LMCPE) carbon paste electrode were appl
