Abstract

The invention discloses a metal complex and its preparation method as well as its application. The metal complex comprises a metal complexant and metal ions. A composition, composed of the metal complex and used for eliminating chemical injuries and chemical hazards, comprises by weight: 0.2-20 parts of metal complex, 1-10 parts of amino acid, 0.1-5 parts of NaC1, 0.1-10 parts of organic acid calcium salt and 0.01-2 parts of bacterial depressant. Non-irritating, non-corrosive and non-allergic to the skin, the composition containing the metal complex is not only used for eliminating hazardous chemicals in the human body, but also used for neutralizing and eliminating leaked hazardous chemicals in the environment.

Description

technical field [0001] The present invention relates to a metal complex, in particular to a metal complex for eliminating chemical damage and chemical hazards, and the present invention also relates to a preparation method of the above metal complex, containing the metal complex for eliminating chemical damage and chemical hazards Composition of chemical hazards and use of the metal complexes in agents for eliminating chemical damage and chemical hazards. Background technique [0002] Human skin or mucous membranes are exposed to corrosive or irritating chemicals that can cause chemical damage. The severity of the injury depends on the nature of the chemical, its concentration, temperature, but also on the duration of contact between the chemical product and the skin. In order to avoid chemical damage, what people first think of is to use a large amount of water to remove chemical substances such as acid and alkali from the surface of the human body, thereby reducing the de...
