钕是稀土催化剂法合成聚乙炔过程中所必需的成分,合成后,钕在聚乙炔中的剩余含量会影响聚合物的稳定性。本文介绍了用同位素稀释亚化学计量法测定聚乙炔中的钕,方法的灵敏度为0.05μg钕。
Neodymium is an essential component in the synthesis of polyacetylene by the rare earth catalyst method. After the synthesis, the remaining content of neodymium in the polyacetylene will affect the stability of the polymer. This paper describes the determination of neodymium in polyacetylene by isotope dilution stoichiometry with a sensitivity of 0.05 μg neodymium.
