On the stoichiometry and stability of americium(III) complexes with a hydrophilic SO-Ph-BTP ligand, studied by liquid-liquid extraction.

1:1 and 1:2 complexes of americium(III) with a hydrophilic anionic SO-Ph-BTP ligand were detected in acidic aqueous nitrate solutions by a solvent extraction method. The determined conditional stability constants of these complexes, log = 4.35 ± 0.

Fluorimetric detector and sensor for flow analysis made of light emitting diodes.

Two compact optoelectronic fluorimetric devices operating according to the paired-emitter-detector-diode concept have been developed. The fluorimetric detector, fabricated of three light emitting diodes only, has been applied for the development of fluorimetric optosensor by further integration with sensing solid phase. In these investigations as a model analyte and as a model sensing layer useful for solid phase spectrometry, riboflavin and C18-silica have been chosen, respectively.
