New Chemical Organic Anhydride Immobilization Process Used on Banana Pseudostems: A Biopolymer for Cation Removal
Maleic and phthalic anhydrides were
chemically incorporated onto
the banana pseudostem biopolymeric structure through reaction without
solvent at the fusion temperatures of the reagents. The new biomaterials
showed unequivocal success for these proposed reactions and demonstrated
abilities to remove cations from aqueous solutions. Phthalic anhydride
pendant chains bonded to biopolymeric structure showed high performance
for cation sorption at short times, 60–180 min, to give the
maximum sorption capacities of 0.52, 0.54, and 0.59 mmol g<sup>–1</sup> for copper, cobalt, and nickel, respectively. Identically, maleic
anhydride chains gave 0.27, 0.32, and 0.20 mmol g<sup>–1</sup> for the same sequence of cations. The equilibrium data were best
represented by the Langmuir model in a linear regression and by the
Freundlich model in nonlinear regression procedures. These new biopolymers
are promising for ecosystem remediation with advantages in using biopolymers
based on a natural, cheap, and abundant raw biomaterial
