The analysis of the metal content of the natural waters of Venice lagoon system, requires a pre-conditioning of the samples. In this way the interferences are eliminated and preconcentration of the trace and sub-trace elements of interest performed. Some of the most reliable procedures for samples pre-conditioning are considered, relevant to some electrochemical (DPASV e DPCSV) and spectroscopic (GFAAS, XRFE, ICP-MS) instrumental techniques. The features of the above instrumentation are compared in terms of number of analytes that can be determined in the same run, cost per element analysis, etc.

Abstract
The analysis of the metal content of the natural waters of Venice lagoon system, requires a pre-conditioning of the samples. In this way the interferences are eliminated and preconcentration of the trace and sub-trace elements of interest performed. Some of the most reliable procedures for samples pre-conditioning are considered, relevant to some electrochemical (DPASV e DPCSV) and spectroscopic (GFAAS, XRFE, ICP-MS) instrumental techniques. The features of the above instrumentation are compared in terms of number of analytes that can be determined in the same run, cost per element analysis, etc.File in questo prodotto:
