This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,564.

Summary of the Inventive Concept

This inventive concept leverages the core technology of hemostatic compositions comprising an anion exchanger and a calcium salt to develop novel applications for environmental remediation, pollution control, and industrial wastewater treatment.

Background and Problem Solved

The original patent focused on hemostatic compositions for bleeding control. However, the limitations of the original patent did not consider the potential of this technology in other fields. This inventive concept addresses the need for effective and efficient methods to remove pollutants, heavy metals, and radioactive isotopes from contaminated soil, water, and industrial wastewater.

Detailed Description of the Inventive Concept

The new inventive concept utilizes the anion exchanger's ability to bind to pollutants, heavy metals, and radioactive isotopes, while the calcium salt enhances the binding capacity. This composition can be applied to various environmental remediation scenarios, including contaminated soil treatment, heavy metal removal from water, industrial wastewater treatment, and surface decontamination. The anion exchanger's matrix can be tailored to target specific pollutants, and the calcium salt concentration can be optimized for maximum binding efficiency.

Novelty and Inventive Step

The new claims introduce a novel application of the hemostatic composition technology, which was not obvious from the original patent. The inventive step lies in recognizing the potential of this technology in environmental remediation and adapting it to address specific pollution control challenges.

Alternative Embodiments and Variations

Alternative embodiments could include using different anion exchangers or calcium salts, modifying the matrix structure, or incorporating additional components to enhance the composition's effectiveness. Variations could also involve adapting the composition for specific industries, such as oil spill cleanup or nuclear waste treatment.

Potential Commercial Applications and Market

This inventive concept has significant commercial potential in the environmental remediation and pollution control industries. Target markets include companies involved in industrial wastewater treatment, contaminated soil remediation, and surface decontamination. The technology could also be applied in various industries, such as oil and gas, mining, and nuclear energy.
