Methylation of humic acids - the impact on the reactivity studied by diffusion techniques

Popis výsledku v původním jazyce

The diffusion cell technique processes of chosen ionic compounds (basic organic dyes ?Rhodamine 6G) was studied in supported hydrogel matrix for the study on reactivity of humic acids (standard samples of humic acids ? International Humic Substances Society ? Leonardite). The reactivity of humic acids was studied by interactions with basic organic dyes by the simple diffusion techniques realized in the diffusion cell. The rate of interactions of humic acids with chosen organic dye was compared by fundamental diffusion parameters such as the lag time (time needed for penetration of organic dye through hydrogel sample), the sorption capacity of humic acids and the effective diffusion coefficients. The reactivity of humic acids especially sorption capacity is strongly dependent on the amount of carboxylic groups. The influence of carboxylic groups was modified by methylation. Carboxylic groups became occupied by methyl groups during methylation, so the sorption capacity and the total reac
