Abstract：The dissolution conditions of Ti80 titanium alloy samples by four acid systems (including sulfuric acid-nitric acid,nitric acid-hydrofluoric acid, sulfuric acid-hydrofluoric acid-nitric acid and hydrochloric acid-hydrofluoric acid-nitric acid) were investigated, realizing the rapid and effective dissolution of Ti80 titanium alloy samples. Then, the content of aluminum, niobium, zirconium, molybdenum and iron in sample solution was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The conditional tests were conducted for four acid dissolution systems. The dissolution conditions for each acid system were preliminarily obtained based on the dissolution phenomenon and the dissolution extent of samples. The dissolution conditions for sulfuric acid-nitric acid system were as follows: the sample was dissolved in 10.0 mL of sulfuric acid (1+1) by heating at 290-310 ℃; after dissolving completely, the nitric acid was added dropwise until the color of solution was faded. The dissolution conditions for nitric acid-hydrofluoric acid system were as follows: 10.0 mL of water was firstly added into sample; then, 2.0 mL of nitric acid and 2.0 mL of hydrofluoric acid were added to fully dissolve the sample. The dissolution conditions for sulfuric acid-hydrofluoric acid-nitric acid system were as follows: 10.0 mL of sulfuric acid (1+3) was firstly added into sample; then, 2.0 mL of hydrofluoric acid was added to fully dissolve the sample; 2.0 mL of nitric acid was added until the color of solution was faded; finally, the solution was heated until fume was observed. The dissolution conditions for hydrochloric acid-hydrofluoric acid-nitric acid system were as follows: 15.0 mL of hydrochloric acid (1+1) was firstly added into sample; then, 1.0 mL of hydrofluoric acid was added to fully dissolve the sample; finally, 2.0 mL of nitric acid was added until the color of solution was faded. According to the dissolution conditions above, the Ti80 titanium alloy sample was dissolved by four acid systems to prepare the sample solution. The stability of aluminum, niobium, zirconium, molybdenum and iron in solution was investigated. The content of these elements was also determined. The results showed that four acid dissolution conditions were applicable for the sample preparation for the determination of aluminum, niobium, zirconium, molybdenum and iron in Ti80 titanium alloy by ICP-AES. The obtained dissolution conditions of four acid systems were all reasonable.
