Abstract
Corn stalk can be used as a potential adsorbent because of its abundance,
cost-effectiveness, and accessible functional groups that allow chemical
modifications. This study aims to synthesize cellulose xanthate alginate
beads (ACX beads) from corn stalks to remove methylene blue from
aqueous solutions. ACX beads with various doses of porogen CaCO3 were
printed using the ionic gelation method, and then characterized using
FTIR, optical microscopy, and SEM-EDX. The results of the FTIR analysis
reported changes in the C-S, C=S, and S-C-S vibrations that indicated the
xanthate formation. Furthermore, as the porogen dose increased, the OH
intensity decreased. The high intensity of the OH group results in a high
swelling process. The results of the optical microscopy analysis showed
that the porogen made the ACX beads spherical. SEM-EDX analysis showed
that the higher the porogen dose, the rougher the surface morphology of
the ACX beads and the larger the pore diameter. The maximum adsorption
capacity was obtained on ACX beads without porogen with a contact time
of 360 hours. The study reveals that the kinetic adsorption followed a
pseudo-second-order kinetic model proposed chemical adsorption. The
larger the porogen, the more crosslinks between the divalent cations and
alginate or cellulose that are formed, inhibiting the bond between the ACX
beads and water and methylene blue, thereby reducing the swelling
process and the adsorption capacity of the ACX beads. In addition, the pore
size that is too large does not match the size of the methylene blue
molecule.
