Disperse yellow 54 (DY54) was adsorbed onto two biopolymers, alginic acid and xanthan.
The adsorption isotherms for the biopolymer-DY54 system showed that the adsorption mechanism can best be described by Zimm-Bragg theory.
UV-Visible, FT-IR and MicroRaman studies suggest that DY54 is bounded to both ...
