Pb Detection in Soil Samples by Electroanalysis: Cyclic Voltammetry and Osteryoung Square Wave Stripping Voltammetry

摘要

Carbon Paste Electrodes (CPE) and Chemical Modified Electrodes (CMEs) are proposed as Pb sensors for soil samples treated with ammonium acetate. The extracted fraction were analyzed by electroanalytical techniques. The use of CPE and CMEs in conjunction with electroanalytical techniques as Cyclic Voltammetry (CV) and Anodic Stripping Voltammetry with Osteryoung Square Wave (OSWSV) showed to be very suitable to analyze the lead content in samples (under 10ppm) of dangerous residues collected from a historically polluted site in Tijuana B.C., Mexico.
