| Abstract: | In this paper, nano-copper powders were prepared by using the copper-ammonia waste water as precursor and N2H4 · H2O as reducing agent. The results show that under the conditions of hydrazine hydrate dosage 3 mol/L, solution pH 10. 0, reaction temperature 75 ℃ , the precipitation rate of copper can reach 98.66%. The composition and size of Nano-copper powders were analyzed by XRD technique and the effect of preparation condition on the stability of Nano-copper powders was discussed. |
