• Description: Conditions of a continuous flow extraction of aluminium acetylacetonate in acetylacetone and aluminium 8-hydroxyquinolinate into methylisobutylketone were studied. The analytical signal of the aluminium chelates present in the organic phase was measured at 309.3 nm using atomic absorption spectrometry with electrothermal atomization (ETAAS) at the flow rate ratio Faq/Forg = 3 for aqueous and organic phases. The acetylacetonate method was applied to the determination of aluminium in real dialysis concentrates.
