Notes:
Experimental parameters for determination of aluminum (up to 15 ppb) were evaluated in acetate (pH = 4.2) and borate (pH = 8.9) buffer solutions. Because the reaction of Calmagite in acetate buffer requires heating (10 min, 90°C) the total analysis time is relatively long. This inconvenience is circumvented by using a borate buffer. The complexation reaction is nonspecific in both media. Iron(III) should be reduced using hydroxylamine hydrochloride, whereas copper(II) and some other metals may be eliminated by electrolysis. The developed method was used for aluminum determination in reference material - flour V-8 (IAEA-Vienna), tap water, and commercial 4% acetic acid before and after boiling in an aluminum pot.
