摘要

提出的研究手稿的目的是回答的问题,pH值如何影响纤维素衍生物的不同化学性质的吸附行为(阳离子纤维素- AHCE;非离子羟乙基纤维素- HEC和阴离子羧甲基纤维素- CMC)在天然膨润土-纳米粘土N-HB表面的吸附。考察了多糖吸附的多样性,确定了吸附过程的机理,表征了吸附层结构和体系的稳定性。采用紫外-可见分光光度法、FT-IR、XRD、SEM-EDS、XPS、zeta电位和热重分析对其进行了研究。除了认知因素外,所获得的结果有可能在水净化和化妆品中稳定胶体悬浮液的生产中找到实际应用。

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.
