  2. Field of the Invention This invention relates to use of zero valent iron and other metals to generate hydroxyl free radicals and undergo subsequent oxidation to destroy organic chemicals and disinfect bacteria.

  3. The inventors have demonstrated the following novel industrial applications of the hydroxyl free radicals Waste water treatment of: Pesticides effluents Domestic waste water Petroleum effluent industries Food industries Hospitals wastewater Disinfections of: Water polluted by bacteria Swimming pool water Analytical methodologies for quality control of carbohydrates in fruits and juices Sucrose Glucose Fructose Ascorbic acid Quality control of formulated drugs

  4. Removal of chemicals: • Phenol destruction in water

  5. 2. GC chromatograms of phenol before (100 ppm) and after reaction with microscale iron powder for 30 min.

  6. Chromatograms Plots MCounts 1.00 0.75 0.50 0.25 0.00 15 20 25 30 minutes 3. GC chromatogram of heptachlor (Pesticide) Heptachlor 340 ppm Heptachlor after reaction 30 min

  7. 4. Petroleum derivative (NAA)

  8. Industrial application 1. Wastewater olive oil industry

  9. 2. Kinetic of olive oil wastewater destruction

  10. Destination of organic chemicals material after the reaction?

  11. Carbondioxide formation

  12. Removal of phenol measured as TOC decrease after ZVIP treatment a Phenol was dissolved in phosphate buffer (0.05 M, pH 4). b The reaction underwent 10 min. c The efficiency was corrected by subtracting the background value (29 mg/L TOC) from the TOC levels after reaction.

  13. Analytical methodologies for Quality control of carbohydrates in fruits and juices

  14. Disinfection of water polluted by bacteria

  15. 0.5 µg river water per plate 1 mL of river water per plate No Fe control No Fe control 3 min treatment 3 min treatment 6 min treatment 6 min treatment
