| Abstract: | Potassium ferrate(K_2FeO_4)flocculant was prepared by the oxidation of hypochlorite in aque- ous system.The influence of the reaction parameters,such as temperature,time,and reagent concentration, on the yield of K_2FeO_4 was studied.And the optimum conditions were obtained:oxidation under 20 oC for 90 min,the concentration of Fe(NO_3)_3.9H_2O was about 5%-10 wt%.At the same time,the structure of K_2FeO_4 was also characterized by FTIR,XRD and UV-vis analysis. |
