摘要
华阳川铀铌铅多金属矿石中矿床的赋矿主岩为火成碳酸岩,采用氧化镁半熔、开水浸取法处理样品,用树脂交换处理溶液减少溶液中盐类含量,选用合适的曲线范围,通过加标回收,采用电感耦合等离子体质谱法对该矿区样品中痕量铼元素进行测定。在称样量为0.5000g,定容体积为25mL,校准曲线相关系数大于0.999的情况下,方法检出限0.3 ng/g,测定下限为1 ng/g。采用实验方法对实际样品中的铼和加标回收率进行测定,回收率达到94.1%~106%。
Huayangchuan uranium niobium lead ore is mainly igneous carbonate rock.The sample is treated with magnesium oxide melt sample and hot waterextraction method.The resin exchange treatment solution is used to reduce the salt content in the solution,and the suitable curve range is selected and recovered by standard addition.Inductively coupled plasma mass spectrometry was used to determine the trace rhenium in the sample of the mine.In cases where the sample quantity is 0.5000 g and the constant volume volume is 25 mL,and the correlation coefficient of the calibration curve is greater than 0.9999,the method detection limit is 0.3 ng/g,and the determination lower limit is 1 ng/g.The recovery rate of rhenium and standard in actual samples was measured by experimental method,and reached 94%~108%.
