摘　　要：高含量铷矿石采用氢氟酸、高氯酸、硝酸、盐酸混合酸在200℃控制电热板上溶解,待到样品剩下1m L时用10m L 1+1王水提取后用称量法定容到100m L的容量瓶中,定量加入镉作为内标元素,用电感耦合等离子体光谱测试,通过测量该元素强度变化以及内标元素强度变化比较得到含量结果。通过加标回收试验得到回收率为97.5%~102%,在国家标准样品测试误差规定范围内,方法的有效测试范围为0.010%~50.00%。High rubidium content ore using hydrofluoric acid and perchloric acid, nitric acid, hydrochloric acid at 200 DEG C temperature control heating board until the samples dissolved, lmL left with 10mL 1＋1 after extraction with aqua regia weighing legal volume to a 100mL volumetric flask, add quantitative cadmium as internal standard element, tested by inductively coupled plasma spectroscopy, by measuring changes the elements of strength and internal standard element strength changes compare the content. Methods the recovery rate was between 97.5%-102% and, and the standard test error was within the specified range. The effective range of the method was 0.010%-50%.
