Replacement of copper with reduced iron powder

In the method of replacing copper with iron, the main factors that cause iron consumption are as follows: acidity of solution, oxygen content in solution, etc.;As the replacement reaction is carried out on the liquid-solid interface, the specific surface and contact time of iron powder are also important factors affecting the replacement. The reduced iron powder particles are larger than the surface and the particles are porous. In the reaction of copper replacement, the reaction efficiency is higher than that of iron particles of other entities.
