Evaluation of zirconium as a permanent chemical modifier using synchrotron radiation and imaging techniques for lithium determination in sediment slurry samples by ET AAS

Atomic spectrometry update. Advances in atomic emission, absorption and fluorescence spectrometry, and related techniques

“…For example, in the presence of a sulfate-containing matrix capable of reacting with PGMs, the best modifier is Pd. Flores et al 260 used synchrotron radiation XRF and SEM for the evaluation of Zr as a permanent chemical modifier for Li determination in slurry samples by ETAAS. Results were used to determine optimal conditions for the analysis of sediment samples.…”

Flame atomic absorption determination of zirconium in glass and refractory bricks after coprecipitation with aluminium hydroxide

“…However, the level of toxicity has been found to be moderately low in both histological and cytological studies [3]. In analytical chemistry, zirconium is consumed as an absorption modifier in ET-AAS alone [4] or with other modifiers [5].…”

Spectrometric and morphological characterization of condensed phase zirconium species produced during electrothermal heating on a graphite platform

“…Recently, other Pt group metals 5 and metals that form highmelting carbides or oxides, such as zirconium, have found favour as permanent modifiers that produce a longer lasting coating on the graphite tube or platform. [6][7][8][9][10][11][12] It has been shown, through various studies, that the permanent modification approach suffers from certain drawbacks as well as providing some successes [13][14][15][16][17][18] in ETAAS, with different and even contradictory mechanisms of the analyte modification process proposed.…”
