The molar absorptivity and Sandell's sensitivity of the coloured species are 3.20*104 L mol-1 cm-1 and 3.6 ng cm-2 respectively. Beer's law is obeyed between 0.25-2.76 g mL-1 of Sn(II)) at 430 nm. The stoichiometry of the complex was found to be 1Č2 (metal: ligand). A highly selective first order derivative spectrophotometric method for the determination of tin is also reported. The developed procedure has been successfully applied for the determination of tin in various alloy samples and synthetic mixtures of some low melting alloys"},{"@xml:lang":"sl","#text":"Razvili smo enostavno, selektivno in občutljivo spektrofotometrično metodo za določevanje kositra(II) z uporabo novega sintetiziranega reagenta diacetilmonoksim p-hidroksibenzoil hidrazona v raztopini s kationskimi površinsko aktivnimi snovmi.
