| Abstract: | NDMA is a new-born disinfection by-product(DBP) and of high carcinogenic risk,so it is becoming the research hotspot in water environment field gradually.Relevant background of NDMA was introduced,and formation mechanism of NDMA including nitrosification and indirect oxidation via unsymmetrical dimethyl hydrazine(UDMH) intermediate was discussed.The treatment technologies of NDMA precursor and relevant research on NDMA precursor were emphatically introduced. |
