Název v původním jazyce

Removal of cyanobacterial amino acids in water treatment by activated carbon adsorption

Popis výsledku v původním jazyce

The applicability of activated carbon for the adsorption of phenylalanine, arginine and aspartic acid from aqueous solution was evaluated in this study. These amino acids are plentiful in low-molecular weight algal organic matter produced by cyanobacteria, which is not satisfactorily removed by chemical coagulation. Equilibrium adsorption of amino acids was studied on well-characterized activated carbons. Adsorption experiments were conducted at various adsorbate initial concentrations, pH values and ionic strengths to elucidate the effect of solution properties on the amino acid removal. Distinct adsorption mechanisms were observed for individual amino acids depending on the pH and the type of carbon applied. Generally, adsorption of amino acids decreased as the ionic strength of the solution increased. The added salt screened attractive electrostatic interactions, altered surface charge of the adsorbents or changed adsorbate solubility.
