ABSTRACT:
The use of reverse osmosis as an alternative or substitute method for the purification of a crude diagnostic agent. In the purification process a crude Ioversol solution is contacted with a cross-linked membrane under pressure, forcing the low molecular weight impurities within the crude Ioversol solution through the membrane pores and retaining Ioversol molecules.
