Abstract
A method for the isolation of humic substances from El Burro Pond (Arg entina) is described. Only fulvic acids are present due to the chemica l composition of the water. The procedure is based on the adsorption-d esorption through a macroporous resin (Amberlite XAD-2), neutralizatio n of the eluate, desalting (Sephadex G-15), ion exchange (Amberlite IR A-120, H-form) and lyophilization. The low ash content of the dried ma terial indicates the effectiveness of the procedure.
