Description
Inimfon Udoetok, Mohamed Mohamed, and Lee Wilson study hybrid chitosan biosorbents for adsorption. Their 2024 paper tunes how these materials capture substances at surfaces and pores. Chitosan is a natural polymer that can be reshaped into sorbents. Cross-linking it with glutaraldehyde changes its structure and behavior. Quaternized forms add further control over charge and swelling.
The team varied reactant ratios and acidity during preparation. Spectroscopy and thermal tests tracked the chemical changes. Surface charge measures showed near-neutral values for modified forms. Swelling in water fell as cross-linking increased. Quaternized forms swelled more than plain cross-linked ones. Dye probes tested how well each form adsorbs. The work fills gaps on how polymer structure drives sorbent performance.
