Application of Anodic Dissolution Technique to Automated Analysis of Metals. Determination of Phosphorus in Copper.

Abstract

experimental situations. In some cases it may still be necessary to perform a primary separation from the bulk material, but there should be no need for individual separations of all elements of interest. The analyses of minerals and rare earth element mixtures are particularly interesting in this regard, and experiments are now in progress to investigate these systems.

Electroanalysis and Coulometric Analysis

“…Several recent reports have appeared on anodization of metallic samples as a method of dissolution and separation. Barabas and Lea (10) used anodic dissolution of a Cu sample at a high current for a short time in an automated colorimetric analysis of P in Cu. Anodic dissolution techniques have also been reported for the analysis of oxide inclusions in The steel sample, connected as an anode, is dissolved into an ammonium citrate electrolyte at a current density of 100 ma.…”

High current-density anodic electrodissolution in flow-injection systems for the determination of aluminium, copper and zinc in non-ferroalloys by flame atomic absorption spectrometry

“…The anodic electro-dissolution approach (AE) [12][13][14][15] has been suggested as an alternative procedure for solid sample dissolution due to its simplicity, low operational cost, portability and feasibility of coupling with flow-injection analysis (FIA) [16]. On-line metallic sample dissolution, based on FIA-ED coupling, is very attractive in analytical routine work involving spectrometric or spectrophotometric determinations [17,18].…”

High current–density anodic electrodissolution in flow–injection systems for the determination of aluminium, copper and zinc in non–ferroalloys by flame atomic absorption spectrometry

“…Although efficient, these accessories are relatively expensive and hardly portable. The anodic electro-dissolution approach (AE) [12][13][14][15] has been suggested as an alternative procedure for solid sample dissolution due to its simplicity, low operational cost, portability and feasibility of coupling with flow-injection analysis (FIA) [16].
