Abstract:The simultaneous determination conditions of aluminum, potassium, iron and vanadium in titanium additive by inductively coupled plasma atomic emission spectrometry (ICPAES) were studied, and accordingly, a determination method was established. The sample was dissolved in sulfuric acid, hydrochloric acid and nitric acid. The analytical lines for aluminum, potassium, iron and vanadium were 396.1, 766.4, 259.9 and 292.4 nm, respectively. Under the optimal conditions, the matrix titanium, sulfuric acid and coexisting elements had no interference in the determination. The detection limit of aluminum, potassium, iron and vanadium was 0.003 0 μg/mL, 0.001 7 μg/mL, 0.002 4 μg/mL and 0.001 4 μg/mL, respectively. The proposed method was applied to the analysis of actual samples, and the found results were consistent with those obtained by titration method or atomic absorption spectrometry. The relative standard deviation (RSD) was less than or equal to 1.5 %. This method could meet the analytical requirements of impurities in aluminum industry additives (titanium agent).
