The low molecular weight organic material originating from the production of cyanobacteria and green algae contain a variety of peptides and free and combined amino acids (AAs) which are poorly removed by coagulation and causes many problems in drinking water treatment. Adsorption onto activated carbon (AC) represents a possibility of how to remove these substances. In this study, we focused on the effect of the solution temperature as another factor that influences the adsorption process. This research evaluated the removal of three AAs (arginine, phenylalanine and aspartic acid) at 10, 18 and 25 °C and pH 5, 7 and 9 using two different activated carbons (FTL, PIC). Adsorption of all investigated AAs was found to be endothermic in nature.
