Prospective application of diethylaminoethyl cellulose (DEAE-cellulose) with a high adsorption capacity toward the detoxification of 2,4-dichlorophenoxyacetic acid (2,4-D) from water

Abstract

Dextoxification of 2,4-D was achieved using DEAE-cellulose.

Tapping the potential of a glucosamine polysaccharide-diatomaceous earth hybrid adsorbent in the solid phase extraction of a persistent organic pollutant and toxic pesticide 4,4′-DDT from water

“…The farm water characteristics and the location coordinates have been reported previously by our group in an earlier study. 53 Approximately, a 25 L volume of water was sampled from an agricultural field having a total hardness of over 1000 ppm and a near neutral pH. The pesticide 4,4′-DDT was not present as such in the sample and hence the adsorption experiments was done by spiking 4,4′-DDT at different concentrations and was found that 90% (Table S3 † ) of 4,4′-DDT was adsorbed onto this hybrid adsorbent surface.…”

Study on isolation methods of natural polysaccharides

“…In DEAE cellulose, diethylaminoethyl groups replace some of the hydrogen atoms in hydroxyl groups. Ion exchange chromatography separates mixture components via the reversible interaction of ionizing agents with the sorbent's ionic groups [37]. Polysaccharides are eluted from the column using salt solutions of varying concentrations.…”

Sustainable synthesis of magnetic Sargassum siliquastrum activated carbon loaded with NiS nanorods for adsorption of 2,4-D herbicide

“…There are several types of adsorbents developed towards the removal of 2,4-D from water with good absorption capacity, e.g., 3dimensional/graphene oxide/Fe 3 O 4 (Hajighasemkhan et al 2022 ), Fe-Zr-based metal–organic frameworks (Liu et al 2022 ), glutaraldehyde-crosslinked chitosan (Li et al 2023 ), bifunctional porous polyethyleneimine-grafted lignin microspheres (Wu et al 2021 ), modified bentonite clay (de Souza and dos Santos 2022 ), diethylaminoethyl cellulose (Kodali et al 2021 ), and UiO-66-NMe 3 + (Wu et al 2020 ). Nevertheless, many of these adsorbent materials show drawbacks like, harsh preparation conditions, high energy consumption, particle agglomeration, and low adsorption capacity.…”
