Naked-eye determination of oxalate anion in aqueous solution with copper ion and pyrocatechol violet.

Jing Su et al.

The Analyst, 135(11), 2918-2923 (2010-09-30)

A novel strategy for the determination of oxalate anions was successfully established using a copper ion and pyrocatechol violet (PV) ensemble. The sensor ensemble can discriminate oxalate over other common anions including F(-), Cl(-), I(-), Br(-), HPO(4)(2-), PO(4)(3-), AcO(-), CO(3)(2-)

Speciation of aluminium in tea infusions studied by size exclusion chromatography with detection by post-column reaction.

A K Flaten et al.

The Science of the total environment, 207(1), 21-28 (1997-12-16)

Aluminium-organic species in tea infusions were studied by size exclusion chromatography, using a Superose 12 HR column, a mobile phase of 0.12 mol l-1 tris(hydroxymethyl)aminomethane adjusted to pH 5.5 and detection by UV-visible spectrophotometry. Aluminium was detected after post-column reaction

On-line preconcentration of copper as its pyrocatechol violet complex on Chromosorb 105 for flame atomic absorption spectrometric determinations.

Berrin Buke et al.

Journal of hazardous materials, 163(2-3), 1298-1302 (2008-09-03)

An on-line solid phase extraction method for the preconcentration and determination of Cu(II) by flame atomic absorption spectrometry (FAAS) has been described. It is based on the adsorption of copper(II) ion onto a home made mini column of Chromosorb 105
