The Influence of Metallic Ions on the Viscosity of Hyaluronic Acid Solutions.

Abstract
K hyaluronate was prepared and appears to be stable in aqueous soln. Ferrous and ferric ions decrease the viscosity. Small cupric ion concns. cause a gel formation; concns. above 10-2 [image] cause a decrease in viscosity. Zn, Hg, Co, Ag, Pb, Mg, Be, Ni and Cr had no effect.
