Abstract

This disclosure relates to inorganic structured metal luminophores for the detection of peroxides and/or free radicals in proximity thereto. The disclosure includes the application of inorganic phosphates or mixtures thereof with one or more metal components that provides a structured metal luminophore capable of providing real-time detection and/or measurement of the presence of peroxides and/or free radicals in an environment proximal to the structured metal luminophore.

First claim

I claim:

1. A structured phosphate luminophore (SPL) or structured metal luminophore (SML) comprising a phosphate scaffold, wherein the phosphate scaffold comprises sodium hexa metaphosphate (SHMP).

2. The SPL or SML of claim 1 , wherein the phosphate scaffold further comprises sodium tripolyphosphate (STPP).

3. The SPL or SML of claim 2 , further comprising a metal component.

4. The SPL or SML of claim 1 , further comprising a metal component.

5. The SPL or SML of claim 4 , wherein the metal component is selected from zinc, calcium, manganese or a combination thereof.

6. The SPL or SML of claim 4 , wherein the phosphate scaffold is provided at 3.0-99.0 weight percent of the SPL or SML and the metal component is provided at 0.1-99.0 weight percent of the SPL or SML.

7. The SPL or SML of claim 6 , wherein the phosphate scaffold is provided at 50 to 90 weight percent of the SPL or SML.

8. The SPL or SML of claim 7 , wherein the metal component is provided at 4 to 40 weight percent of the SPL or SML.

9. The SPL or SML of claim 2 , wherein the metal component comprises manganese and at least one of zinc and/or calcium.

10. The SPL or SML of claim 9 , wherein the phosphate scaffold is provided at 3.0 to 99.0 weight percent of the SML, manganese is provided at 0.1 to 99.0 weight percent of the SPL or SML and the at least one of zinc and/or calcium is provided atl to 16 weight percent of the SPL or SML.

11. The SPL or SML of claim 10 , wherein the phosphate scaffold is provided at 50 to 90 weight percent of the SPL or SML.

12. The SPL or SML of claim 10 , wherein manganese is provided at 4 to 40 weight percent of the SPL or SML.

13. A method for monitoring and/or detecting and/or quantifying the presence of a free radical or peroxide in an environment comprising:
placing the SPL or SML of claim 1 in the environment;
exposing the SPL or SML to the free radical or peroxide in the environment; and
detecting with a detector electromagnetic radiation emitted from the SPL or SML when the free radical or peroxide is in proximity to the SPL or SML.

14. The method of claim 13 , wherein the environment is a container of edible fat, edible oil, lipids or petrochemicals.

15. The method of claim 12 , wherein the detector is selected from a luminometer, a fluorescence meter, a photometers, or a combination thereof.

16. A hydrocarbon solution comprising the SPL or SML of claim 1 .

17. The hydrocarbon solution of claim 16 , wherein the solution comprises at least one of an edible oil, an edible fat, a lipid, or a petrochemical.
