Simultaneous Degradation of Cu(II) and Cr(VI) in the Micro-Polluted Water by Potassium Ferrate

Abstract:

This Experiment study on the simultaneous degradation effect of Cu(II) and Cr(Ⅵ) in the micro-polluted water by potassium ferrate. And the influential elements on the removal effects and probed into the degradation mechanism was analyzed. The results indicated that the removal rates of Cu(II),Cr(Ⅵ) by synergetic effect of potassium ferrate oxidation and coagulation were 76.2%、62.2%,respectively,when the optimizing conditions were as follows: oxidation pH was 7,oxidation time was 20min,flocculation pH was 9,flocculation time was 30min and dosage of potassium ferrate was 40mg/L.
