DETERMINATION OF NI(II) IN ALLOYS USING A NEW REAGENT DERIVED FROM L-DOPA
A simple and sensitive UV-Vis spectrophotometric method was developed using a new chromogenic reagent, L-dopasemiquinone, for the quantification of Ni(II) in metallic alloys: Inox, Co-Cr, and Ni-Ti. The complex [Ni(II)(L1-)3]1- presents an intense band at 591 nm, ε = 2.4 x 103 L mol-1 cm-1. Beer’s l...
