A column solid-phase extraction method for the preconcentration and determination of
cadmium (II), copper (II), cobalt (II), iron (III), lead (II), nickel (II) and zinc (II) dithizone …

A novel, simple method based on magnetically assisted chemical separation (MACS) has
been developed for analytical purposes. In this method, neocuproine modified magnetic …

5-Tert-butyl-2-hydroxy-benzaldehyde oxime (L1) and 3, 5-di-tert-butyl-2-hydroxy-
benzaldehyde oxime (L2) are synthesized and characterized by conventional spectroscopic …

The applicability of silica gels for the application in solid-phase extraction was tested. Silica
was modified with ketoimine groups. Surface characteristics of the modified silica were …

Abstract N, N′‐bis (salicylidene)‐1, 2‐phenylenediamine (salophen) modified activated
carbon was prepared and used as an effective sorbent for solid phase extraction of Cu (II) …

This paper describes our research on the synthesis of the sorbent with chemically bonded
ketoimine groups, and, furthermore, using this sorbent in the SPE technique to extract and …

Bis (salicylidenamino) ethane loaded onto sodium dodecyl sulfate‐coated alumina was
used as a new chelating sorbent for the preconcentration of traces of Pb (II) and Cu (II) prior …

Modified carbon paste electrodes based on amino acid (l-ornithine) or curcumin (turmeric)
as ionophores and o-nitrophenyl octyl ether (o-NPOE) as solvent mediator were prepared …

A new chelating resin, 2-hydroxybenzaldehyde thiosemicarbazone loaded XAD-4, was
synthesized and characterized by FT-IR and elemental analyses. The synthesized resin was …

The use of chemically modified XAD-4-1, 2-bis (o-aminophenylthio) ethane chelating resin
for preconcentrating Cr^{6+}, Mn^{2+}, Fe^{3+}, Co^{2+}, Cu^{2+}, Cd^{2+}, Zn^{2+} …
