Flame AAS determination of dopants and trace metal impurities in single crystals of potassium titanylphosphate (cas 12690-20-9)

Add time:08/23/2019    Source:sciencedirect.com

A flame AAS method is used for the determination of dopants and impurities in potassium titanylphosphate (KTP) single crystals. Sample digestion using sulphuric acid and hydrofluoric acid is proposed as being the most appropriate procedure. The effect of major and minor components in the sample solution on the analytical signal is studied. The content of the dopants Cr, Mn and Ni (at a level of about 1 mg g−1) as well as the content of the impurities Fe, Na, Mg, W and Al (from 4 μg g−1, depending on the trace metal) in the KTP single crystals is determined. The precision of the method is characterized by a relative standard deviation of 3–10%. The accuracy is checked by comparison with ICP-AES data for the trace element content in the KTP single crystals.
