摘要
先用硝酸+氢氟酸溶解磷酸锆银钠样品,再加氨水(1+1)使其转换成氨性溶液,然后用原子吸收分光光度法测定磷酸锆银钠中的银,本法测定结果与火试金法测定结果一致,相对标准偏差小于0.37％,回收率大于95％。
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. Finally
the 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%.
