Disclosed is a method for degrading cannabinoid, wherein the method carries out a photocatalytic reaction on a liquid containing cannabinoid, the method specifically comprising: (1) a photocatalytic reaction; (2) filtering; and (3) recycling of a photocatalyst. After the liquid containing the cannabinoid is treated using the method, the cannabinoid content is obviously reduced and can reach ppm-level. The raw materials and reagents used in the method are cheap and easy to obtain, the operation and testing methods are simple, and the photocatalyst can be recycled, avoiding waste of resources, and facilitating industrialization.

There are disclosed processes for destructing a toxic chemical including the steps of mixing the toxic chemical with a liquid phase formed by an aqueous mixture of water and an ionic liquid or molten salt which is miscible with water, the ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting the toxic chemical in the liquid phase with the ionic liquid or molten salt so as to decompose the toxic chemical.

The present invention is directed towards a composition for decontaminating surfaces contaminated with toxic chemicals/substances, comprising at least one type of metal oxyhydroxide such as zirconium hydroxide, Zr(OH).sub.4, optionally with added water for hydration of the solid, mixed into a carrier liquid used for application to a contaminated surface.

The present invention provides a composition and a method of using the composition to decontaminate surfaces or objects that have opioid contamination, and in particular to decontaminate fentanyls on surfaces using an opioid-active reagent and an opioid-effective solubilizing agent. Preferably, the opioid-active reagent is chlorine dioxide.

A method of destructing a toxic chemical, comprising the steps of mixing said toxic chemical with a liquid phase formed by an aqueous mixture of water and an ionic liquid or molten salt which is miscible with water, said ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting said toxic chemical in said liquid phase with said ionic liquid or molten salt so as to decompose said toxic chemical. The ionic liquid or molten salt comprises a tertiary amine group or quaternary ammonium group. The dispersion or solution further contains at least one oxidizing agent and a donor of hydrogen bonds. Decontamination of contaminated surfaces and decomposition of toxic substances are achieved by using environmentally friendly, non-toxic solvents and reactants which yields reaction products which are substantially non-harmful or even non-toxic.
