在乏燃料后处理流程中,钚的还原反萃过程一般采用硝酸羟胺做还原剂、硝酸肼做支持还原剂,其含量需要严格控制,因此,建立快速测定硝酸羟胺和硝酸肼含量的分析方法是十分必要的。目前采用容量法及分光光度法相结合的方法测其含量,但该方法过程复杂,操作费时。近红外光谱法测定硝酸羟胺和硝酸肼,无需分离,可直接测量,简单快速,并可实现对两种组分的同时测量。 In the spent fuel reprocessing process, the reduction and stripping of plutonium generally use hydroxylamine nitrate as a reducing agent, hydrazine nitrate as a support reducing agent, its content needs to be strictly controlled, therefore, the establishment of rapid determination of hydroxylamine nitrate and hydrazine nitrate content analysis method Very necessary At present, the volumetric method and spectrophotometry are used to measure the content, but the method is complicated and time-consuming to operate. Near-infrared spectroscopy for the determination of hydroxylamine nitrate and hydrazine nitrate, without separation, can be measured directly, simply and quickly, and enables simultaneous measurement of both components.
