ABSTRACT:
A process for removing carboxylic acids from aqueous solutions using a composition of a polyaluminum chlorohydrate and a cationic polyelectrolyte is described. After or during the initial contact of the aqueous solution with the composition, an organic liquid may optionally be added after which separation into an aqueous phase and an organic phase occurs whereby the organic acids are removed in the organic phase. The preferred polyaluminum chlorohydrate is aluminum chlorohydrate, and the preferred cationic polyelectrolyte is a high molecular weight poly(dimethyl diallyl) ammonium chloride.
