Atomic Spectrometry Update – a review of advances in environmental analysis

Abstract

This review covers advances in the analysis of air, water, plants, soils and geological materials by a range of atomic spectrometric techniques including atomic emission, absorption, fluorescence and mass spectrometry.

Digestion Procedure and Determination of Heavy Metals in Sewage Sludge—An Analytical Problem

“…In the case of decomposition of sewage sludge, organic substances are the main components of the matrix. Also, the destruction of other types of matrix creates problems with the choice of the digestion method [34,36,42]. Generally, digestion of samples by method B (microwave mineralization of roasted sludge) allows extraction of the highest amounts of zinc, lead, nickel and chromium in both raw and stabilized sludge.…”

Direct determination of lanthanides by LIBS in REE-rich ores: comparison between univariate and DoE based multivariate calibrations with respect to spectral resolution

“…This design is, however, best suited for a small concentration range (0-2 mg L À1 in ref. 47) due to the number of samples growing as n 2 regardless of the number of factors (e.g., 20 2 in the present work and 5 2 in ref. 47).…”

“…Rare-earth elements (REEs) have numerous applications in high-tech industries 1 and the determination of REE concentrations is an essential task for geochemical exploration studies, mining, etc. 2 Inductively coupled plasma mass spectrometry (ICP-MS) is a common analytical method used to accomplish this task due to the wide dynamic range and low detection limits. [3][4][5] Inductively coupled plasma optical emission spectrometry (ICP-OES) is a feasible alternative to ICP-MS in some cases.…”

Atomic spectrometry update: review of advances in elemental speciation

“…This latest update adds to that from last year 1 and complements the five other annual Atomic Spectrometry Updates, advances in environmental analysis 2 , advances in the analysis of clinical and biological materials, foods and beverages 3 , advances in atomic spectrometry and related techniques 4 , advances in X-ray fluorescence spectrometry and its special applications 5 and advances in the analysis of metals, chemicals and materials. 6 Two books have appeared in the most recent review period containing chapters dealing with elemental speciation topics.…”

“…The Part 2 experiment consisted of injecting 1 µL of a V porphyrin compound into an acetonitrile carrier stream flowing at 400 µL min -1 that passed first through a UV detector and then into the ICP-MS. Peak broadening was calculated as variance in units of µL 2 . Amazingly, values ranged from 10 to 8,000.…”
