The niobium content in a tantalite mineral was determined by ICP spectroscopy using the standard addition method. 0.1068 g of the mineral sample was accurately weighed off, heated to 900°C in the presence of Na2PO4/NaH2PO4(flux), dissolved in water and diluted to 100 ml. Different volumes of a 1000 ppm standard Nb solutions were next added to 15 ml tantalite solutions and diluted to 100 ml. The emission data that were obtained for the different solutions are reported in the following table. Volume of unknown Volume of Nb standard Corrected intensity of emission 15.0 0.0 44.683 15.0 0.10 46.677 15.0 0.2 48.959 15.0 0.3 51.385 15.0 0.5 55.378 Calculate the mass % of the Nb in the original mineral sample, using the above mentioned results as well as the % Nb205 in the mineral
