TL;DR: In this article, a simple, selective and reliable method for rapid extraction and determination of trace amounts of Cu (II) ions from aqueous samples using octadecyl-bonded silica membrane disks modified with bis-(3-methoxy salicylaldehyde)-1,6-diaminohexane and flame atomic absorption spectrometry (FAAS) is presented.

TL;DR: Four platinum(II) complexes of Schiff bases derived from salicylaldehyde and 2-furaldehyde with o- and p-phenylenediamine were reported and characterized based on their elemental analyses, IR and UV-vis spectroscopy and thermal analyses (TGA) and activity data show that the platinum( II) complexes are more potent antimicrobials than the parent Schiff base ligands against one or more microorganisms.

TL;DR: In this paper, a new synthesized Schiff base, (Z)-2-((1 H -1,2,4-triazol-3-ylimino)methyl)phenol, was synthesized to apply as an efficient ionophore in electrochemical responses of the potentiometric sensor for the determination of Ce(III) ions in aqueous solutions.
Abstract: The ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, [BMP]Tf 2 N, as the binder, multi-walled carbon nanotubes (MWCNTs), silica nanoparticles, graphite powder and also a new synthesized Schiff base have been used to fabricate a new carbon composite electrode with very attractive sensing behavior. New Schiff base, (Z)-2-((1 H -1,2,4-triazol-3-ylimino)methyl)phenol, was synthesized to apply as an efficient ionophore in electrochemical responses of the potentiometric sensor for the determination of Ce(III) ions in aqueous solutions. This potentiometric sensor responds to Ce(III) ions in the wide linear range of 2.00 × 10 −8 to 1.00 × 10 −1 mol L −1 with a Nernstian slope of 19.79 ± 0.10 mV decade −1 . The detection limit of 6.45 × 10 −9 mol L −1 was obtained at pH range 3.0–7.5. It has a fast response with response time of about 5 s, and can be used for at least 17 weeks without any considerable divergences in the potentials. The proposed sensor thus allows sensitive, selective, simple, low-cost, and stable electrochemical sensing of Ce(III) ions in the presence of a large number of alkali, alkaline earth, transition and heavy metal ions. Such abilities promote new opportunities for determining Ce(III) ions in a wide range of real samples.
