近些年来,沥青逐渐发展为重要的化工原料,作为涂料的原料是其用途之一,尤其是用于军事器材方面。因此要求多方面了解沥青中的成份,例如铅、锰的含量。铅在某些沥青中含量甚微。为了配合科研工作的开展而且结合现有的分析条件我们选用了极谱分析的催化示波极谱方法进行了一些试验,以适应测定要求。 In recent years, asphalt gradually evolved into an important chemical raw material, as a coating raw material is one of its uses, especially for military equipment. Therefore, it is required to know the contents of asphalt in many aspects, for example, the contents of lead and manganese. Lead in some asphalt content is very small. In order to cooperate with the development of scientific research and combined with the existing analysis conditions, we selected the polarographic analysis of the catalytic oscillopolarographic method to conduct some experiments to meet the measurement requirements.
