The effects of different parameters and the nitric acid concentration on sensitivity repeatability elemental analysis were characterized for liquid electrode plasma optical emission spectrometry (LEP-OES). In addition, internal standardization LEP-OES was investigated. developed method used determination lithium, potassium, iron, zinc in aqueous solutions samples with high concentrations after ...

In this study, Differential Pulse Polarography (DPP) method was preferred of Cd (II) and Pb levels, which have toxic effects. This applied to determine levels in cold-pressed olive oil brought from 5 different provinces Turkey. The samples were dissolved microwave digestion using concentrated HNO3 H2O2. Analyses carried out acetate buffer (pH 4) EDTA added. LOD for found as 0.74, 0.52 µg L-1 th...

Microwave digestion-inductively coupled plasma astigmatism (ICP-AES) was used to analyze the contents of mineral elements (including K, P, Mg, Ca, Na, Fe, Cu, Mn, B, Zn, Se, Li) in 54 Olecranon Peaches collected from Shangping town, Lianping County. The obtained data analyzed by Correlation analysis (CA), combined with fruit reducing sugar (RS%), sugar-acid ratio (S/A) and sensory scores. resul...

Introduction: This study was carried out to determine elements (Li, Na, K, Mg, Ca, Ba, B, Al, Si, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Ag and P) in the Suaeda vermiculata (S. vermiculata) and Suaeda aegyptiaca (S. aegyptiaca) in three different regions of Southern Iran using inductively coupled plasma optical emission spectrometry (ICP-OES) after microwave-assisted acid digestion. Materials and ...
