Enrichment of trace amounts of copper(II) ions in water samples using octadecyl silica disks modified by a Schiff base ionophore prior to flame atomic absorption spectrometric determination

Determination of cadmium(II) ion by atomic absorption spectrometry after cloud point extraction

“…For instance, Schiff base ligands are used as a modifier of octadecyl membrane disks for separation and concentration of trace amounts of metal ions [11]. These ligands have been also used in CPE methodology [15,17]. In the present work, we show that the ligand L 22pysa (Fig.…”

“…The selectivity and efficiency of the method depend directly on the complexing ability of the lipophilic ligand. Schiff base ligands bearing nitrogen and oxygen donor atoms have been shown to exhibit interesting ionophoric properties, in particular toward heavy metal ions, and their applications in different separation and preconcentration techniques have been investigated [15,16]. For instance, Schiff base ligands are used as a modifier of octadecyl membrane disks for separation and concentration of trace amounts of metal ions [11].…”

Gold Microelectrode Arrays Based Electrode for Determination of Trace Copper in Seawater

“…As a typical heavy metal, copper plays an important role in human beings since it is an essential component of several enzymes and it can help the Fe transportation [3][4][5] . However, excessive absorption of Cu 2+ can create health risks such as the blood and kidneys problems and also make large influence on the growth of plants, such as the shortened root length, fewer leaves and decline in the plants biomass 6 .…”

Cloud point extraction and flame atomic absorption spectrometry determination of trace amounts of copper(II) ions in water samples

“…Their application in different separation and pre-concentration techniques were investigated. As instance, Schiff base ligands are used as modifier of octadecyl discs for separation and concentration of trace amount of metal ions [16]. This class of metal ion receptors has been also used as phase transfer agents of metal ions in liquid-liquid extraction [17] and transport through liquid membranes [18].…”

“…In continuation to our studies on the ion receptor properties and analytical applications of N x O y -type Schiff base ligands [16,18,[20][21][22], we describe here the application of N,N 0 -bis(2-hydroxyacetophenone)-1,2-propanediimine (L) (Fig. 1) plexing agent for the cloud point extraction of trace amounts of Cu 2+ ions in water samples, and subsequent determination by flame atomic absorption spectrometry (FAAS).…”
