| Abstract: | Two digestion methods of solution and alkali for dealing with a niobium tantalum ore sample melting by acid, determination of inductively coupled plasma atomic emission spectrometry, the detection limit of the method for the determination of calculation： Nb2O5 =0.71μg/g, Ta2O5 1.41 μg/g, the two kinds of digestion method accuracy and precision were compared, and the results were basically consistent, which can meet the requirements. The advantages and disadvantages of the two kinds of digestion method were discussed. |
