| description | The invention discloses application of ionic liquid functional silica gel to removing phenolic pollutants in waste water and belongs to the technical field of treatment of industrial waste water. According to the technical scheme, the application of the ionic liquid functional silica gel to removing the phenolic pollutants in the waste water includes the specific steps that the ionic liquid functional silica gel is added into the phenolic pollutant waste water and stands for 1h at room temperature so that the phenolic pollutants in the waste water can be adsorbed; then the ionic liquid functional silica gel used for adsorption is separated, a methanol/water/acetic acid mixed solution is added into the ionic liquid functional silica gel subjected to separation, standing and soaking are performed for 1h at room temperature, clear liquid is separated, soaking is repeated three times, and regenerative ionic liquid functional silica gel obtained after cleaning and drying is repeatedly used for adsorbing the phenolic pollutants in the waste water. The adsorption efficiency of the ionic liquid functional silica gel to the phenolic pollutants in the industrial waste water is high, the adsorption capacity is large, and the ionic liquid functional silica gel is prone to regeneration and recycle. |
