Adsorption Mechanisms of Cellulose Derivatives with Different Chemical Nature on Bentonite - pH Perspective.
The goal of this study is to answer the question of how pH influences the adsorption behavior of cellulose derivatives with different chemical natures (cationic cellulose-AHCE; nonionic hydroxyethyl cellulose, and anionic carboxymethyl cellulose) on the surface of the natural adsorbent bentonite-nanoclay N-HB. The diversity of polysaccharide adsorption is investigated, the mechanisms of this process are determined, and the adsorption layer structure as well as the stability of the systems are characterized. The studies are carried out by UV-vis spectrophotometry, Fourier transform infrared, X-ray diffraction, scanning electron microscopy-electron dispersive spectroscopy, X-ray photoelectron spectroscopy, zeta potential, and thermogravimetric analysis. Apart from the cognitive element, the results obtained have the potential to find practical applications in water purification and in the production of stable colloidal suspensions in cosmetics.
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
