Non-oxidized mercury cleaning agent and application thereof

The invention discloses a non-oxidized mercury cleaning agent and application thereof. The non-oxidized mercury cleaning agent comprises the following components: (1) dialkyl dithiophosphonate; (2) an oily solvent system; wherein the dialkyl dithiophosphonate has a molecular structure as shown in a formula I: # imgabs0 # molecular structure, R1 and R2 are the same or different and are respectively and independently selected from linear or branched C1-C6 alkyl groups, M represents a cation, and m is 1-4. The mercury cleaning agent shows a very good cleaning effect, the cleaning time can be shortened, the mercury content in equipment is reduced to a safe range, the equipment can be manually repaired and maintained, the mercury content in the equipment reaches the standard after attached mercury is cleaned, and the mercury cleaning rate is larger than 90%. In addition, equipment is not corroded, and the safety of the equipment is guaranteed. 本发明公开了一种非氧化汞清洗剂及其应用。非氧化汞清洗剂包含下列组分：(1)二烷基二硫代次膦酸盐；(2)油性溶剂体系；其中，二烷基二硫代次膦酸盐
