The present invention relates to a process for purification of iodinated X-ray contrast agents and in particular to purification of crude dimeric contrast agents, such as Iodixanol and Ioforminol. More particularly, the invention relates to purification of such X-ray contrast agents using membrane technology to remove monomeric impurities.
