Abstract: Activated carbon powder was selected as the detergent and nitrobenzene was used as the adsorption object to simulate the water phase leakage. By means of constant temperature water bath oscillation heating, UV spectrum, control variables and other methods, the amount of nitrobenzene washed by activated carbon powder in water phase is accurately obtained, and the corresponding equations are calculated by combining the theoretical models of washing kinetics and washing isothermal mechanism, and the washing mechanism and influencing factors are deeply studied. It is concluded that the removal of nitrobenzene by activated carbon powder is not only a physical adsorption process, but also influenced by internal chemical distribution and electronic interaction.

Key words: nitrobenzene, aqueous phase washing, activated carbon, emergency rescue
