Transport of Organic Dyes in Systems Containing Humic Acids

This work is focused on transport organic dyes in systems containing humic acids as active reaction agent. Methylene blue was usedas a model organic dye which can behave as pollutant and influence many processes in nature. Transport of pollutants in nature isstrongly affected by interactions with humic acids or natural organic matter. Their influence is dependent on affinity of pollutant tocontent and strength of active binding sites. Two different humic samples are used in this study in order to compare their propertieson transport of organic dye. Both humic acids are used in original extracted form as well as in the form of samples with selectiveblocked functional groups.
