Study on Ti Determination in Sc_2O_3 by Spectrophotometry AITranslate
Abstract AITranslate
Ti content in Sc2 O3 was determined by spectrophotometry. Sc·O3 is decomposed by hydrochloric acid,Cu,Co and Ni are separated by NH3 · H2O precipitation,Ti is separated from Sc with H2C2O4 saturated solution,and then Ti content can be determined with the colorimetric method based on the yellow complex generated between Ti4＋ and H2O2 in 0.9-1.8 mol/L H2SO4 medium. The dosage of H2C2O4 and H3PO4 was investigated. This method is suitable for the determination of 0.01%-0. 50% TiO2 content in Sc2O3, and both its standard addition recovery and precision are in line with experimental requirements.
