Visual Colorimetric Analysis for Niobium Content of the Potassium Fluotantalate AITranslate
Abstract AITranslate
Nb2O5 liquor is added into the Ta2O5 to form standard solution,then carry out chromatographic separating on paper after series of treatment with potassium fluotantalate sample parent solution.Finally directly take visual colorimetric analysis with sample by this method.The standard error and relative error and is 0.000 104% and 5.5%,respectively recovery is 97%～103%.It is applicable for the sample containing niobium 0.001～0.0x%.
