Electrochemical Determination of Lead (II) ION Using 4-(6-Phenyl-7h-[1,2,4] Triazolo[3,4-B][1,3,4]Thiadiazin-3-Yl)Aniline Reagent

Abstract

The electrochemical properties of the reagent 4-(6-phenyl-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-3-yl)aniline were investigated using cyclic voltammetry and amperometric techniques. An electrochemical method for the determination of lead(II) ions was developed and optimized. The influence of different solvents, including acetic acid, pentyl alcohol, butyl alcohol, and ethyl alcohol, on the determination of lead(II) ions was studied. It was found that the oxidation of lead(II) ions increases with higher acidity, with the highest oxidation observed in acetic acid. The half-wave potential in acetic acid was determined to be 0.3 V. Furthermore, the complex formation reaction between 4-(6-phenyl-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-3-yl)aniline and lead(II) was shown to occur at a rate of 4.8 per second. These findings provide insights into the electrochemical behavior of the reagent and its potential for lead(II) ion detection.
