Název v původním jazyce

Transport Characteristics of Some Carboxylic Acids in the Polymeric Anion-exchange Membrane Neosepta-AMH: Batch Experiments

Popis výsledku v původním jazyce

This article reports the transport of selected carboxylic acids ? citric acid, oxalic acid and tartaric acid ? through an anion-exchange membrane (Neosepta-AMH) in a two-compartment dialysis cell. These basic data have been completed by measurements of the sorption isotherms. The mass-transfer rate has been quantified by the following transport characteristics: the overall dialysis coefficient, the permeability of the membrane, and the membrane mass transfer coefficient. The sorption experiments have revealed that the Neosepta-AMH membrane exhibits the highest affinity to tartaric acid, whereas the lowest affinity has been found for citric acid. The analysis of the mass transfer data has shown that the membrane studied is relatively well permeable foroxalic acid: all three transport characteristics for oxalic acid are approximately 1 order of magnitude higher than those for citric or tartaric acid.
