Synthesis and application of sugarcane bagasse cellulose mixed esters. Part I: Removal of Co and Ni from single spiked aqueous solutions in batch mode using sugarcane bagasse cellulose succinate phthalate.

Sugarcane bagasse cellulose mixed ester succinate phthalate (SBSPh) was synthesized by a novel one-pot reaction method. The effects of temperature, time and mole fraction of succinic anhydride (χ) on the responses weight gain (wg), number of carboxylic acid groups (n), and adsorption capacity (q) of Co and Ni were evaluated by a 2 experimental design. The chemical structure of the material was elucidated by Fourier transform infrared, C Multiple Cross-Polarization solid-state NMR spectroscopy and H NMR relaxometry.
