Interactions between humic acids and emerging contaminants in wastewater

Popis výsledku v původním jazyce

Pollution of wastewater and surface water by organic compounds is a serious environmental problem.Pharmaceuticals and addictive substances represent a significant group of emerging contaminants thatenter a large amount of wastewater and associated ecosystems. Paracetamol and caffeine are widely usedcompounds and their presence in wastewater indicates the degree of pollution caused by human activity.The removal of these polluting substances from water is difficult and they, therefore, become persistentin the environment. Humic acids are natural organic substances formed by the decomposition of mainlyplant residues and are abundant in soil, peat, coal, and some waters. Humic acids can interact physicallyand chemically with a wide range of organic substances. To determine the kinetics of the interactionsbetween humic acids and selected drugs, we extracted humic acids from lignite. Batch sorptionexperiments with HPLC measurement of drug concentration and surface plasmon resonance method wereused for the determination of kinetic parameters. Both paracetamol and caffeine interacted with extractedhumic acids that confirms the ability of humic acids to influence the behaviour of simple organic moleculesin wastewater, surface water, or soil.
