Interference in anodic stripping voltammetry from the Teflon vessels used in pressurized digestion
1Department of Chemistry, University of Oslo, Box 1033, Blindern, Oslo 3, Norway.
Abstract:
The insufficient inertness of Teflon vessels towards acids at high temperature and pressure is shown to be the source of some interferences in anodic stripping voltammetry. To avoid such problems the use of Pyrex glass inserts in Teflon-lined steel bombs is proposed for the determination of non-volatile heavy metals. The procedure is easily applied to commercially available digestion bombs. Blank values and recovery tests for blood samples spiked with Cd, Pb and Cu are given, and the completeness of the digestion has been checked.

ASV is used to determine metals and metalloids at trace levels. It involves two steps: deposition and stripping. First, a negative potential is applied to the...
Atomic Absorption Spectroscopy: Interference
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...
