Agent, can recycle Fe on its surface simultaneously3+, the hydroxide precipitation reducing ferrum in course of reaction generates[3], there is effect
Good, low cost and the advantage such as environmentally friendly.Iron filings can dissolve slowly and discharge ferrous ion, can effectively activate
Persulfate produces potentiometric titrations and comes degradation of dye active blue 19 and organic compound[4-6].Therefore iron filings activation persulfuric acid
Salt oxidation processes is polluted and is paid close attention to widely[7-9].Iron filings are under conditions of aerobic or anaerobism, it is possible to by the corruption of iron filings
Erosion dissolving discharges ferrous ion, and in acid condition, this process is the quickest[10].Iron filings discharge ferrous iron slowly
Ion can activate persulfate and produce free radical, not only avoid too much ferrous ion and potentiometric titrations reaction,
Causing the consumption of free radical, the Direct electron transfer of iron filings can also activate persulfate and produce free radical simultaneously[11].Iron filings are filled out
Filling reaction column after being passed through persulfate, its reaction equation is as follows:
Research report according to H.Kusic et al.[12], at optimum conditions, Fe0/S2O8 2-And Fe2+/S2O8 2-System pair
The mineralization rate of pollutant is respectively 53.36% and 34.89%, it is clear that the effect activating persulfate with iron filings can compare
Good.Existing research is primarily directed to beaker experiments and carries out, it is adaptable to intermittent duty process and laboratory lab scale.And industrial often
Continuous running, also lack corresponding processing equipment and technique.
