چکیده مقاله:

Ionic associates of basic fuchsin have been used as electrochemical sensing probe for the potentiometric determination of ۲,۴-dichlorophenoxyacetic acid (۲,۴-D) and ۴-chlorophenoxyacetic acid (۴-CPA). 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 ۲,۴-D (۴-CPA) in an analytical range of ۱×۱۰-۴ to ۳×۱۰-۲ M with LOD as ۱۰-۵ M. For ۲,۴-D ISE, a hyper-Nernstian function was observed. The sensors have been applied for the determination of ۴-CPA and ۲,۴-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.
