    AnotaceFree and combined amino acids (AAs) can be found in all types of natural waters including water sources used for drinking water production. AAs form together with peptides and proteins a dominant fraction of nitrogenous compounds of algal organic matter (AOM) (Pivokonsky et al., 2014). Many deleterious effects on water treatment are related to AAs presence in raw water (increase Cl2 consumption during chlorination, production of taste and odour compounds, potential source of biodegradable organic carbon, precursors of disinfection by-products) (Hureiki et al., 1994, Froese et al., 1999, Gagnon et al., 2000, Freuze et al., 2005, Hong et al., 2009). A coagulation-based treatment is often ineffective in removing organic compounds of high polarity and low molecular weight (MW) such as AAs, so it is necessary to pay attention to the removal of AAs from raw water sources. Adsorption onto activated carbon (AC) seems to be an appropriate method since it is effectively applied in drinking water production for the uptake of other organic nitrogenous compounds with a very low MW (Kopecka et al., 2014). The aim of this study was to investigate the effect of adsorbate initial concentration and pH on the adsorption of three amino acids belonging to the major AAs commonly identified in natural waters containing AOM and also in treated water after coagulation/flocculation – aromatic phenylalanine (Phe), basic arginine (Arg) and acidic aspartic acid (Asp).
