The literature on metal ion speciation in solid matrices is reviewed, taking into account its
applications in the analysis of soil, sediment, biological materials, foodstuff and other solid …

The microwave plasma torch (MPT), as a relative new source, has found extensive use in
atomic spectrometry. In this review, the fundamental features and characteristics of the MPT …

Technological progress is a constant feature these days of any area of human activity.
Chemical analysis, which is indispensable for quality control in all branches of industry …

The removal of heavy metals from wastewater by using activated alumina or chitosan as
adsorbers was evaluated. Cd (II) and Cr (III) were employed as models of the behaviour of …

A flow injection on-line sorbent extraction system was studied in conjunction with flame
atomic absorption spectrometry to determine cadmium, copper and lead in digest solutions …

The solvent extraction of gold, palladium, technetium, indium and rhenium from both
mixtures of a deep eutectic solvent with aqueous salt solutions and of two different aqueous …

Solid-phase extraction (SPE) approach was introduced approximately five decades ago,
and until then development of SPE materials is seamlessly continued. Lately, the SPE …

Two manifold designs were evaluated. Water samples and wine digests in 10% nitric acid
were pumped through a column containing a commercially available resin (Pb-Spec®), an …

Whereas flame atomic absorption spectrometry (AAS) lacks sensitivity at analyte
concentrations below 0.1 and 10 μg g− 1 in analyses of liquid and solid samples …

In the present study, chitin isolated from locally available shrimp shells was pulverized to
obtain three different particle sizes and then deacetylated to obtain various deacetylation …
