The present application relates to a process for removing an organic compound having one or more positive charges from an aqueous solution, comprising the steps a) provision of the aqueous solution comprising the organic compound and of a hydrophobic organic solution which comprises a liquid cation exchanger, where the liquid cation exchanger is hydrophobic, and where the liquid cation exchanger has one or more negative charges and an overall negative charge, b) contacting the aqueous solution and the organic solution, and c) separating off the organic solution from the aqueous solution.

Liquid cation exchanger

The invention relates to a method for removing an organic compound having one or more positive charges from an aqueous solution. Said method consists of the following steps a) the aqueous solution containing the organic compound, and a hydrophobic organic solution which contains a hydrophobic liquid cation exchanger having one or more negative charges and a negative total charge, are provided, b) the aqueous solution and the organic solution are brought into contact with each other and c) the organic solution is separated from the aqueous solution.
