在裂变~(99)Mo生产工艺流程建立过程中,通常使用稳定Mo,而不是放射性的~(99)Mo,进行大量条件实验以确定工艺流程,因而建立稳定Mo含量的测定方法非常重要。目前,Mo含量的测定主要有分光光度法、重量法、容量法、原子吸收光谱法等,其中应用广泛的是分光光度法。分光光度法以硫氰酸盐分光光度法最为典型。硫氰酸钾作为Mo的显色剂,在硫酸介质中显色效果好。在酸性介质中,用还原 In the process of fission ~ (99) Mo production process, it is very important to establish stable Mo content by using stable Mo, instead of radioactive 99 Mo, and conducting a large number of experiments to confirm the process flow. At present, the determination of Mo content spectrophotometry, gravimetric method, volumetric method, atomic absorption spectrometry, which is widely used spectrophotometry. Spectrophotometry with thiocyanate spectrophotometry most typical. Potassium thiocyanate as a developer of Mo, in sulfuric acid medium color effect. In acidic media, with reduction
