本文详细地介绍了古埃(Gouy)精密磁秤的仪器装置及其基本原理,并用该装置测定了电解银催化剂的磁性数据,研究了铁杂质含量对电解银磁化率的影响,根据磁化率对磁场强度倒数的线性关系,探索了磁性数据与催化剂反应活性的对应关系,提出了用磁测量作为电解银催化剂质量鉴定方法的可能性。
In this paper, the instrument of Gouy precision scale and its basic principle are introduced in detail. The magnetic data of the silver catalyst is measured by this device. The influence of iron impurity on the magnetic susceptibility of electrolytic silver is studied. According to the magnetic susceptibility The relationship between the magnetic data and the reactivity of the catalyst was explored. The possibility of using magnetic measurement as the quality identification method for the silver catalyst was proposed.
