| Abstract: | Ag_xNa_yH_(1-x-y)Zr_2 (PO_4)_3 is firstly dissolved into nitric acid and hydrofluoric acid,then ammonia water(1+1) is added to convert the resultant into ammoniac solution. Finallythe silver from Ag_xNa_yH_(1-x-y)Zr_2 (PO_4)_3 is determined by atomic absorption spectropho-tometry. The results from this method are in conformity with those from the fire assaying,with the relative standard deviation less than 0. 37% and the recovery over 95%. |
