Abstract :This experiment examines the influence of ionic strength up to equivalent of that of seawater on the absorption value of the aluminum-tiron complex. The study was carried out in distilled water, seawater and diluted seawater 2, 5, 10, 100 and 1000 times dilution. The result shows that the absorption in seawater is 1.2 times higher than in distilled water but for 10, 100 and 1000 times diluted seawater the values obtained are almost the same as in distilled water. Statistical evaluation shows that there is strong correlation between Al concentration and absorption in all solutions, hence the method can be applied to quantify mononuclear aluminum even in aqueous media with high ionic strength (0.69), so the method can be applied even for sea water.
