Nitrite efficient degradable material as well as preparation method and application thereof

The invention relates to a nitrite efficient degradable material. The nitrite efficient degradable material comprises palladium-loaded tourmaline, a reducing metal and a porous spongy material. A preparation method mainly comprises the following steps: (1) preparing the palladium-loaded tourmaline A; (2) preparing a porous spongy material precursor B; (3) after mixing the palladium-loaded tourmaline A and reducing metal powder, adding to the porous spongy material precursor B, foaming, washing, and drying to obtain the soft and elastic nitrite efficient degradable material. A synergistic effect of the palladium-loaded tourmaline and the reducing metal in the prepared nitrite efficient degradable material has a function of degrading nitrite, the porous spongy material has a covering effect,the practicability is improved, and the nitrite efficient degradable material has a good and stable nitrite degradation property in a water body. A reaction is performed for half an hour in 60 DEG C,so a degradation rate of
