As a vital sample preparation method for ¹⁴C graphite, the Zn-Fe reduction method has been widely used in various laboratories. However, there are still few studies on the experimental conditions for the preparation of ¹⁴C graphite with this method. In this work, ¹⁴C graphite samples were prepared based on the Zn-Fe method, and the experimented key parameters such as the reduction reaction temperature, reaction time, reagent dosage, Fe powder activation, and other factors were investigated and determined. The results provide important instructions for the preparation line of ¹⁴C graphite at GXNU lab.
