Adsorptive recovery of geniposidic acid from gardenia yellow pigment extraction wastewater by anion exchange: equilibrium, thermodynamics and mechanism modeling and simulation

Adsorption behavior of gardenia yellow pigment on embedded spherical cellulose adsorbent

“…According to the shape and change of adsorption isotherm, the relationship between adsorbents and adsorbates can be explored. 37,38 The relevant parameters could be seen in Table 3, the Langmuir and Freundlich isotherm model were all t the experimental data, and the correlation coefficients (R 2 ) were higher than 0.995. Both saturated adsorption capacity (q e ) and Langmuir constant (b) increased with an increase of temperature, indicating that high temperature was conducive to the adsorption of GYP on SABW.…”
