Abstract: To develop more efficient chemical methods for the demineralization
of organic pollutants from water bodies, which one was also mimic to the
nature, a degradation of methylene blue by Fe (III) and
H_2O_2 in the absence of light instead of
Fe (II) and H_2O_2 was studied. Results
showed that use of Fe (III) is more promising than Fe (II). The present study
reflects that Fenton reaction is more efficient, in the presence of a small
amount of salicylic acid is added which is a one of the priority pollutant.
