Interaction of some metal ions with fulvic acid isolated from marine environment.

V. M. Desai,Elizabeth Mathew and A.K. Ganguly

Fulvic acid is soluble in alkali, acid, water and also in sea water. Solubilization and/or complexation of Zn, Mn, Co, Fe, Zr, Th and Pu by a fuivic acid extracted from a marine sediment is studied in ammoniacal medium. Most of the elwnents (except Zn) were found to be associated with the fulvic acid in non-cationic complex forms. The elements were also observed to be associated in different states of combination with fulvic acid.
