▎ 摘　　要

NOVELTY - Degradation of N-nitrosodimethylamine involves providing water to be treated containing N-nitroso-dimethylamine, and adding graphene hollow nanospheres loaded with zero-valent iron nanomaterials and potassium persulfate to the water body. The water body to be treated is transferred to the dark condition, and stirred to react followed by degrading N-nitrosodimethylamine. USE - Method for degradation of N-nitrosodimethylamine. ADVANTAGE - The method enables degradation of N-nitrosodimethylamine in efficient manner by improving the reproducible degradation efficiency of nanomaterials with zero-valent iron loaded on graphene hollow nanospheres.
