Removal of iron from water using hydrogen peroxide

الملخص EN

The presence of iron is probably the most common water problem facing by consumers.

So, the aim of this study was to assess the efficacy of hydrogen peroxide to remove iron (Fe2+) from water.

Water with high content of Fe2+ (20 ppm of iron II) was prepared in the laboratory using Iron(II) sulfate heptahydrate (FeSO4.7H2O), then treated with 0, 0.1, 1, 3, 5, 10 and 20 ppm of hydrogen peroxide as the final concentration in the solution for contact time 5, 10, 20, 30 and 60-minute.

Results showed that the average of removal ratio of Fe2+ was 85% -96% at the normal pH range of drinking water.

The recommended dose of hydrogen peroxide was 0.1 ppm as a final concentration for 20-minute contact time.

The study proved that hydrogen peroxide successfully used for Iron II removal and consider as economic and eco-friendly solution.
