摘要
利用先低温预熔,再高温熔融的熔样方法,采用一次沉淀过滤分离法直接检测氮化钒铁中铁含量。结果表明,该方法避免了传统间接差减法操作繁琐、费时费工和结果准确度低的缺点,大幅度提高了检测速度,且测定数据重现性好,准确度高。
It is a method of direct determination of iron content in ferrovanadium nitride,with one-precipitation-filtration-separation step.In the test,the samples first premelt at low temperature and then fuse at high temperature.Compared with the traditional indirect subtraction method,which has complex and time-consuming operation and low accuracy,this method proves to be very rapid and has good reproducibility and accuracy.
