Iron replacement method was applied to deal the copper containing wastewater, the spectrophoto-metric method was used to measure the copper ion contents in the solution before and after the displacement reac-tion. The effects of iron powder dosage, reaction time, reaction temperature and p H on copper replacement ratio were studied. The experimental results indicated that the optimal replacement conditions were as follows： dosage of iron powder was 700mg/50 m L, reaction time was 15 min, react...
