Abstract: The paper mainly introduces Zn0, Zn2+, Fe2+, Fe0, Cd0, S, remnant Jiao Li and so on, should make the zinc phase analysis.Plans to soak with the (NH4)2SO4-NH4OH solution takes in the separation test specimen ZnO and the metal zinc, the EDTA capacity law determination zinc.This law is fast, the analysis result reappears, the accuracy is high.Has provided the real useful analysis data for the craft personnel ingredient.

Key words: zinc ash, EDTA, ZNO
