A new and direct method for the trace element determination in cauliflower by differential pulse polarography

Determination of Metals and Metalloids in Wine Using Inductively Coupled Plasma Optical Emission Spectrometry and Mini-torch

“…The lower content of Se in digestion samples could be related to oxidation of the metal under the influence of HNO 3 and/or could be connected to losses during evaporation depending on the acid composition. This fact was also observed in the determination of Se in the biological materials and cauliflower samples after digestion with acid mixture, containing HNO 3 (Somer and Nakisci Ünlü 2006;Somer and Ünal 2004).…”

Trace element residues in eggshells of grey heron (Ardea cinerea) and black-crowned night heron (Nycticorax nycticorax) from Nallihan Bird Paradise, Ankara-Turkey

“…However, the metal contents were too small in amount and no meaningful result was obtained. Further determinations were carried out by Square Wave Stripping Voltametry (SWASV) using CHI 660 B Electrochemical Analyzer equipped with BAS cell stand (Somer and Ü lkü 2004). The working and auxiliary electrodes were hanging mercury drop electrode (HMDE) and Pt wire and the potentials were measured against Ag/ AgCl (3 M KCl) reference electrode.…”

Study on erythrosine-phen-Cd(II) systems by resonance Rayleigh scattering, absorption spectra and their analytical applications

“…The method research for the determination of cadmium ion also has the vital significance. Recently, the methods for determining Cd(II) mainly include spectrophotometry [5][6][7], atomic absorption spectrometry (AAS) [8], fluorospectrophotometry [9,10], inductively coupled plasma mass spectrometry (ICP-MS) [11], high performance liquid chromatography (HPLC) [12], electrochemical method [13][14][15][16], etc. Each method has its own advantages and disadvantages.…”

“…Fluorospectrophotometry [9,10] is inexpensive, but it refers to tedious synthetic procedures [9] or the sensitivity is lower [10]. Electrochemical methods [13][14][15][16] posses sensitivity and selectivity, whereas the modification of the electrode made the analysis time-consuming. Here in this paper, simple and quick methods of molecular spectrometry including resonance Rayleigh scattering (RRS), dual-wavelength overlapping resonance Rayleigh scattering (DWO-RRS), second order scattering (SOS), frequence doubling scattering (FDS) and spectrophotometric method were developed to determine Cd(II) with high sensitivity and good selectivity.…”
