Humic substances from sediments of Lobos Pond (Argentina). Isolation, characterization and limnological implications

Mostrar todas las versiones(3)

Humic substances (HS) were isolated from the sediments of Lobos Pond (Argentina) using mild conditions to preserve their native structure. The HS (humic and fulvic acids) were characterized by means of elemental analysis and FTIR spectroscopy. Also a by-product obtained during fulvic acids (FA) frac...
