Sažetak
Aluminium has been shown to be harmful for human beings when it is taken in excess. Accumulation of aluminium in the bone and brain tissue has been associated with a series of clinical disorders including encephalopathy, osteodystrophy and microtic anemia [1]. Therefore in most European countries the maximum aluminium concentration in drinking water and infusion fluids should not exceed 200 and 10 mg l-1, respectively. Consequently, the detection limit of analytical methods for aluminium determination in such samples must be lower. The reaction of N'-salicylidene-3-pyridinecarbohydrazide with Al(III) in the water/dioxane medium resulted in the formation of a fluorescent complex with excitation and emission maxima at 383 and 460 nm, respectively. The method developed by using this reaction featured a linear range of the dependence of the emission intensity on a concentration up to 40 mg l-1 Al(III). The detection limit was 2 mg l-1 Al(III). Good selectivity and repeatability were achieved.
