Precise Determination of Iodine in Soil Samples by ICP-MS with Carius Tube and Standard Addition Method Carius管溶样-标准加入电感耦合等离子体质谱法测定土壤中碘
Samples were digested in Carius tube and Os was separated using mini-distillation and purified with micro-distillation method. Re was separated using anion exchange chromatography. 化学流程包括Carius管溶样,小型蒸馏分离Os,微蒸馏纯化Os,阴离子交换法分离、纯化Re。
Chemical procedures for Re and Os separation include: Carius tube is used to digest rock samples, Os is separated by CCl4 solvent extraction and purified with micro-distillation method, and Re is separated through anion exchange chromatography. 岩石样品的Re和Os化学分离采用Carius管溶样法,结合CCl4萃取以及微蒸馏的方法分离纯化Os,利用阴离子交换树脂的方法分离纯化Re。
