Problems solved by technology

[0006] However, since ZnO nanomaterials also have certain toxic effects, and heavy metal Cd exerts toxic effects through multiple mechanisms and multiple pathways, the antagonism of heavy metal Cd toxicity by a single ZnO nanomaterial is still very limited. of

Abstract

The invention discloses a method for resisting against heavy metal Cd toxicity on the basis of a ZnO / GO composite nanomaterial. The method comprises the following steps: 1) compounding a ZnO / GO composite nanomaterial; 2) culturing model cells; 3) exposing the model cells in the ZnO / GO composite nanomaterial and heavy metal Cd; 4) detecting antagonistic efficiency. Through the technical scheme disclosed by the invention, the organism Cd poisoning can be specifically and effectively prevented and detoxified.

Description

technical field [0001] The invention relates to the field of materials for antagonizing heavy metal toxicity, in particular to a method for antagonizing heavy metal Cd toxicity based on ZnO / GO composite nanomaterials. Background technique [0002] Heavy metal Cd is widely used in many fields such as metal plating, battery preparation, paint, printing and pigment production. In addition, the mining, use and combustion of fossil fuels will also cause a large amount of heavy metal Cd to be released into the environment. Smoking, intake of air, food and water polluted by heavy metal Cd will cause heavy metal Cd to accumulate in the body. Since the half-life of heavy metal Cd in the organism is as long as 10-30 years, it is difficult to completely degrade and excrete the heavy metal Cd that enters the body. In addition, the toxicity concentration of heavy metal Cd is very low, and the accumulation of heavy metal Cd in the body caused by various acute or chronic exposures It wil...
