CHARACTERIZATION OF THE DISSOLVED ORGANIC MATTER PRESENT IN THE WATER OF THE BÍO-BÍO RIVER, VIII REGION OF CHILE

The dissolved organic matter in rivers has different origin and its composition can vary both by natural conditions and the anthropic activity that takes place near rivers. This mobile fraction of the organic matter is composed of sub-fractions of different molecular weight and polarity, which confe...
