|COSMOS as absorbent material for dye removal|
|Written by Elza Bontempi|
COSMOS showed unexpected characteristic of dye absorption: it was employed to extract color for example from fruit juice and coca-cola (see the following picture, reporting the drinks after and befor COSMOS employ as adsorbent).
The adsorptive behavior of COSMOS is currently under quantification using methylene blue (MB) as dye model compound. In the following picture COSMOS was employed to remove dye (MB in an incresing concentration).
