Isolation and purification of fulvic acids from a pampasic pond (Argentina)

A method for the isolation of humic substances from El Burro Pond (Argentina) is described. Only fulvic acids are present due to the chemical composition of the water. The procedure is based on the adsorption-desorption through a macroporous resin (Amberlite XAD-2), neutralization of the eluate, des...
