Modified magnetic nanoparticles with catechol as a selective sorbent for magnetic solid phase extraction of ultra-trace amounts of heavy metals in water and fruit samples followed by flow injection ICP-OES

Microchemical journal (Print), 2018
A simultaneous and fast method was explored for extraction of heavy metal ions from aqueous samples based on magnetic solid phase extraction (MSPE). Fe3O4@catechol nanoparticles were successfully fabricated to coat catechol onto super paramagnetic iron ...

Determination of Trace Elements in Turkish Wines by ICP-OES and HG-ICP-OES

2010
The aim of this work was to determine the concentration of toxic metals in wine samples from different regions in Turkey using ICP-OES and HG-ICP-OES, and comparing the results with reports from other researchers. Ten samples each of white wines and red wines were obtained at a local supermarket and analyzed for Ca, K, Cr, Mn, Sn, Zn, Cu, Fe, Ni, Mg ...

Use and limitations of ICP-OES in wine analysis

Mikrochimica Acta, 1989
At present, some 50 inorganic components in wine can be detected, of which 8 are mineral matter at concentrations down to 1 mg/l, about 25 are trace elements with concentrations of 0.001–0.1 mg/l, and about 20 are ultratrace elements at concentrations below 1 μg/1.

Determination of rhodium: Since the origins until todayICP-OES and ICP-MS

Talanta, 2007
Rh is contained in catalyst in much smaller quantities than Pt. For this reason, the database for this metal with respect to emissions from catalytic converters is much smaller than that for platinum, thus precluding a quantitative risk assessment. Accurate determinations of the rhodium have always been difficult tasks.

The application of ICP-OES to industrial analytical problems

TrAC Trends in Analytical Chemistry, 1982
Abstract ICP optical emission spectroscopy was introduced for multi-element determinations some 15 years ago. Nowadays, its field of application covers the analysis of widely differing materials at every stage of industrial activity.

Trace Element Determination Using ICP-OES

2022
Inductively coupled plasma-optical emission spectroscopy coupled with the benefits of solution chemistry serves as an excellent tool in trace element analysis (TEA) because of its multielement capability, large dynamic range of four to six orders of magnitude, and very high temperature in the range of 7000–10 000 K resulting in virtually complete ...
