Abstract

Transition metal ions have the ability to increase the oxidation performance of the inorganic peroxy salts at room temperature by possibly lowering their activation energy or by producing more reactive free radicals. When two transition metal salts are used together to decompose dipersulfate, it provides synergistic oxidation activity, better than obtained by dipersulfate or dipersulfate with either copper or zinc alone. The transition metals mentioned are the water soluble salts of copper and zinc. Oxidation performance of sodium dipersulface in presence of catalytic amount of copper and zinc salts was determined by measuring the destruction of crystal violet dye at a wavelength of 589 nm.

Claims (14)

1. A process for the treatment of recirculating water by adding thereto a composition comprising sodium dipersulfate, 0.5 to 5% by weight based on the composition of copper sulfate or copper citrate and 2 to 10% by weight based on the composition of zinc sulfate which provides synergistic oxidation activity in the presence of an oxidizing sanitizer.

2. The process according to claim 1 , wherein the oxidizing sanitizer present in the water is a source of hypochlorous acid.

3. The process according to claim 1 , wherein the combination is copper sulfate pentahydrate or copper citrate in an amount of from 0.5 to 5% by weight of the composition, and zinc sulfate heptahydrate in an amount of 2 to 10% by weight of the composition.

4. A composition of matter comprising sodium dipersulfate and copper sulfate or copper citrate and zinc sulfate, wherein the copper sulfate or citrate is present in an amount of 0.5 to 5% by weight of the composition and the zinc sulfate is present in an amount of 2 to 10% by weight of the composition.

5. A method for improving the activity of a peroxy compound in a composition containing sodium dipersulfate comprising adding to the composition an amount of copper sulfate or copper citrate and zinc sulfate to provide a composition containing from 0.5 to 5% by weight of the composition of copper sulfate or citrate, and from 2 to 10% by weight of zinc sulfate.

6. A sanitizing composition comprising a mixture of a halogen source material, sodium dipersulfate and a combination of copper and zinc transitional metal ions as a catalyst source wherein copper is present as copper sulfate or copper citrate in an amount of 0.5 to 5% by weight of the composition and zinc is present as zinc sulfate in an amount of 2 to 10% by weight of the composition.

7. The composition of claim 6 , in which the halogen source material is sodium or potassium dichlor, tricolor, calcium hypochlorite and/or lithium hypochlorite.

8. The composition of claim 6 , in which boron is an optional component.

9. The composition of claim 8 , where a boron source material is selected from the group consisting of boric acid, boric oxide (anhydrous boric acid) and compounds having the formula M N B X O Y .ZH 2 O, in which M=sodium, potassium, calcium, magnesium or ammonium, n=1 to 3, X=any whole number from 2 to 10, y=3x/2+1, z=0 to 14.

10. The composition of claim 9 , wherein the boron source material is present in amount up to 20% by weight of the composition.

11. The composition of claim 6 , in which a clarifier source material is present for water treatment.

12. The composition of claim 11 , in which the clarifier source material is aluminum sulfate or sodium aluminum sulfate.

13. The composition of claim 12 , wherein the aluminum sulfate or sodium aluminum sulfate source material is present in amount of up to 20% by weight of the composition.

14. A composition of matter for the treatment of a water system to inhibit growth of micro-organisms comprising sodium dipersulfate and as a catalyst a combination of 0.5 to 5% by weight based on the composition of copper sulfate or copper citrate and 2 to 10% by weight based on the composition of zinc sulfate to improve the oxidation properties of the sodium dipersulfate at ambient temperature.
