| 摘要 |
Use of a porous, preferably dimensionally stable, material for the extraction of hydrophobic constituents, such as benzene, toluene, xylene and/or chlorinated hydrocarbons, from an aqueous solution, the material containing a hydrophobic substance exhibiting great affinity for the constituents to be extracted from the water, characterised in that the material has a surface which will be wetted more readily by the hydrophobic substance immobilised in the pores having an average diameter in the range of 0.1 to 50 (my)m than by the aqueous solution, with the proviso that at least 60 % of this substance can be extracted from the pores by a liquid wholly made up of the constituents to be extracted. |
