Study on Adsorption and Desorption Performance of Reactive Dyes on Anionic Exchange Membrane

Abstract:

The adsorption and desorption performance of Reactive Brilliant Red K-2BP and Reactive Brilliant Red K-2G on anionic exchange membrane were studied. The adsorption and desorption performances of anionic exchange membrane under different conditions were compared. The results showed that the adsorption accords with the pseudo-second dynamics model. Langmuir adsorption model could well describe adsorption processes. The addition of inorganic salt Na2SO4 in the dye solution had certain influence on the adsorption. The desorption percentage could reach above 80% using the mixture of ethanol, sodium chloride and water solution as desorbent, and the anionic exchange membrane could be reused.
