| 摘要 |
The invention relates to a process for the treatment of an aqueous mixture comprising a dipolar aprotic compound, comprising: a) an adsorption step, in which the aqueous mixture is brought into contact with a porous adsorbent, whereby the porous adsorbent is chosen such that the dipolar aprotic compound adsorbs to it more readily than water; b) a desorption step, in which the porous adsorbent is brought into contact with a desorbing agent, whereby a recovery solution is formed comprising the desorbing agent and the dipolar aprotic compound. |
