On-line Preconcentration and Determination of Zinc Using Zincon and Flame Atomic Absorption Spectrometry

On-Line Fabric Disk Sorptive Extraction via a Flow Preconcentration Platform Coupled with Atomic Absorption Spectrometry for the Determination of Essential and Toxic Elements in Biological Samples

“…The figures of merit of the proposed FI-FDSE-FAAS method and other selected on-line SPE methods coupled to FAAS [8,10,12,14,15,18,24,[30][31][32][33][34][35][36][37][38][39][40][41][42][43], are compiled in Table S1 (Supplementary Materials). The proposed method features good sensitivity and precision with better or similar detection limits than earlier works for Cu(II) [8,15,31,32,34], Ni(II) [8,[38][39][40], Zn(II) [41][42][43], Pb(II) [8,24], and Cd(II) [24] assays, using a shorter preconcentration time.…”

A reliable determination of zinc levels in beverages with and without alcohol by flame atomic absorption spectrometry after cloud point extraction

“…Its determination requires sufficiently sensitive techniques for detection at trace/ultratrace levels. Recently, the zinc levels of different beverages with and without alcohol by different detection techniques such as spectrophotometry, 9,10 Xray uorescence spectrometry (XRF), 11 total reection X-ray uorescence spectrometry (TR-XRF), 12 derivative potentiometric stripping analysis (derivative PSA), 13 anodic stripping voltammetry (ASV), 14 atomic uorescence spectrometry with hydride generation (HG-AFS), 15 inductively coupled plasma optical emission spectrometry (ICP-OES), 16 atomic absorption spectrometry with electrothermal atomization (ET-AAS), 17 ame atomic absorption spectrometry (FAAS) [18][19][20][21][22][23][24][25] were investigated in detail. These techniques were successfully applied to the determination of zinc levels in different beverages with their advantages and disadvantages.…”

Synthesis and application of ion-imprinted polymer for extraction and pre-concentration of iron ions in environmental water and food samples

“…However, FAAS techniques has limited by less sensitivity and depending on the level of analyte to be determined[17,18].mildly distributing the powder sample onto the stainless steel stubs, using SEM (Philips, XL30) instrument. To investigate the surface area of Fe(III)-IIP and BET-N 2 sorption studies Quantachrome NOVA instrument was employed in this work.…”
