Application of adsorptive stripping voltammetry based on PbFE for the determination of trace aluminum released into the environment during the corrosion process.

Abstract：

:This work presents a new fast and sensitive method for voltammetric determination of Al(III) as Al(III)-cupferron complexes, which was used for the analysis of solution after exposure of aluminum alloy AA2024. Experimental conditions of voltammetric measurement such as preconcentration time, potential, and operating parameters were optimized. The formed Al(III)-cupferron complexes were adsorbed on an in situ plated lead film electrode (PbFE) using the potentials of -1.2 V (15 s) and -0.7 V (60 s) versus Ag/AgCl electrode. The promising results were obtained in 0.1 mol L-1 ammonia buffer at pH = 8.15 and 6 ∙ 10-5 mol L-1 Pb(II), 3 ∙ 10-4 mol L-1cupferron. The calibration graph was linear from 1 ∙ 10-10 to 2 ∙ 10-7 mol L-1 with the calculated detection limit of 3.3 ∙ 10-11 mol L-1, repeatability with RSD of 4.9% (n = 5). The accuracy was established by analysis of the synthetic sample.
