在分析化学教学与文献中,已采用以SI国际单位制为基础的名称和符号。但现有分析化学教材,大多援引传统的“当量”概念,产生与SI单位不协调的问题。就此IUPAC分析化学学组曾提出推荐意见,似应予重视并试行采用。 SI引入摩尔这个物质的量基本单位后,传统的“克当量”单位,应与“克分子”、“克原子”、“克离子”等一并废用。考虑到分析工作中习惯用当量概念简化计算,IUPAC推荐在需用当量概念时如何 In analytical chemistry teaching and documentation, names and symbols based on the SI system of units have been adopted. However, most existing analytical chemistry textbooks mostly invoke the traditional concept of “equivalence”, resulting in problems that are not coordinated with SI units. In this regard IUPAC Analytical Chemistry Group has made recommendations, it seems that we should pay attention to and pilot adoption. After SI introduces the basic unit of molar quantity of this substance, the traditional unit of “equivalent gram” should be used together with “mole”, “gram atom” and “gram ion”. Taking into account the simplistic calculation of customary equivalent concepts in analytical work, IUPAC recommends how to use equivalent concept
