Influence of the membrane composition on electroanalytical characteristics of the electrodes has been established. Effect of the modifying additive (N,N,N',N'-tetramethylethylenediamine) on the chemical and analytical characteristics of the electrodes is shown. The sensors can be used for the determination of 2,4-D (4-CPA) in an analytical range of 1×10-4 to 3×10-2 M with LOD as 10-5 M. For 2,4-D ISE, a hyper-Nernstian function was observed. The sensors have been applied for the determination of 4-CPA and 2,4-D in model solutions of pesticide preparations.The ion-selective electrode may be efficiently used in either model or real samples, providing a low detection limit detection; The electrode may be made more efficient, if the lypophylic basic additive is used for electrode production. Its addition has significant importance for the electrode response.}, keywords = {2,4-Dichlorophenoxyacetic acid,4-Chlorophenoxyacetic acid,Potentiometry,Ion-selective electrodes,Modifying additives}, url = {https://www.analchemres.org/article_152523.html}, eprint = {https://www.analchemres.org/article_152523_9ab7b3b520597820008d3ded8c831fb4.pdf} }
