“…The thermodynamic constants ΔH and ΔS for chlorophenols adsorption onto CHIT/ALG-PEIPPAA were calculated from the slopes and intercepts of the linear variation of (lnK d ) vs (1/T) by the following expression (Eq. 10) (Ferrah et al 2022).…”

“…They contain one or more covalently chlorine atoms, which can be divided into ve groups namely: mono-chlorophenols (MCPs), dichlorophenols (DCPs), trichlorophenols (TCPs), tetrachlophenols (TeCPs) and pentachlorophenols (PCPs) (Fan et al 2015;Garba et al 2019). The increasing of the social and political concern on environment consists a more rigorous control of industrial wastewaters by using green technologies and natural resources (Ferrah et al 2022;Munoz et al 2016). Adsorption is the most commonly employed method due to its effectiveness and economic advantages (Dabrowski et al 2005;Hameed et al 2008;Oh et al 2011).…”

A trifunctional polysaccharide structure based on a biodegradable matrix, Chitosan/Alginate-PolyEthylene-Imine-Phenyl-Phosphonamidic Acid (CHIT/ALG-PEIPPAA) was synthesis via a condensation reaction, using glutaraldehyde as cross linking agent. The aim of this research work is to investigate the chlorophenols adsorption in the batch process from an aqueous medium. The influence of several parameters like pH, time reaction, initial concentration, and ionic strength was followed carefully in this study. Scanning electron microscopy (SEM) micrographs show a heterogeneous morphology with different particle sizes of agglomerates around a few micrometers, and irregular particles shape. The FTIR spectrum and Zeta potential characterization confirms the presence of several hydrophilic groups and a high positive charge around 31.4 mV for CHIT/ALG-PEIPPAA surface adsorbent. The optimum pH solution for chlorophenols removal was reached at an initial pH of around 4.4. The maximal adsorption capacity was found to be 118 mg.g− 1, and 249 mg.g− 1 under optimum conditions for 4-chlorophenols and 2–4 chlorophenols respectively. The kinetic modeling followed the pseudo-second-order rate expression for both chlorophenols molecules. Thermodynamics data leads to an exothermic and spontaneous adsorption process (∆H = − 6.98KJ.mol− 1; ∆H = − 2.74KJ.mol− 1), respectively for 4-chlorophenols and 2–4 chlorophenols. The regeneration process of CHIT/ALG-PEIPPAA is more favorable in the presence of hydrochloride acid (2.0 mol.L− 1), up to 78%, and 91% of desorption yield for 4-chlorophenols and 2–4 chlorophenols, respectively.

Pharmaceuticals are used to improve the lives of people across the globe. The high demand for their fabrication and use causes a very serious environmental threat since their presence is ubiquitous in aqueous matrices. For this reason, the synthesis, characterisation, and efficiency of three chitosan-based materials to eliminate pharmaceutical mixtures from aqueous solutions were examined in the present study. The target mixture comprised seven widely used drugs: carbamazepine, cyclophosphamide, adefovir, levofloxacin, metronidazole, glibenclamide, and trimethoprim. The grafting of poly(ethylene imine) and poly(acrylamide) on the chitosan structure allowed its physical characteristics to be controlled. An adsorption assessment was performed at different pH values, and it was concluded that pH = 4 was the optimum value. The adsorption kinetics revealed that the adsorption of a drug mixture involves a combination of physical and chemical adsorption. The adsorption process appeared to be finished after 1 h for all compounds of the studied mixture, with CS-AMI exhibiting the fastest kinetics. Mass adsorption experiments were also carried out to determine its effects. Overall, the grafting process significantly increased the adsorption capacity over the pristine material. Specifically, the highest capacity increase for CS-PEI was ~220% for carbamazepine, and for CS-AMI, it was 158% for trimethoprim. FT-IR, SEM, and XRD were used for the characterisation of the polymers. Based on the findings, the three materials are suggested as very effective adsorbents for the elimination of medicine residues from aqueous matrices.

“…Alginate is an anionic polymer, that has non-toxic, biodegradable, biocompatible properties, and the anionic properties of alginate can interact with the cationic properties of chitosan to form more stable nanoparticles [11]. Ferrah et al [12] reported chitosan combined with alginate and polyethyleneimine methylene phosphonic acid to be able to be a promising and efficient adsorbent for removing the pharmaceutical compounds sodium diclofenac and ibuprofen from wastewater.…”

Paracetamol contained in wastewater can cause adverse effects on animal ecosystems, such as fish living in waters and cause harmful effects on humans. Adsorption techniques are used to remove these pharmaceutical compounds. Alginate-chitosan nanoparticles are non-toxic and effectively used as adsorbents to remove pharmaceutical compounds in wastewater. Research on glutaraldehyde crosslinked alginate-chitosan nanoparticles as paracetamol adsorbent has been carried out. This research used the ionic gelation method. Nanoparticles were characterized using transmission electron microscopy (TEM), scanning electron microscope (SEM-EDX) and Fourier transform infra-red spectrophotometer (FTIR). Furthermore, the nanoparticles were used for paracetamol adsorption. The results showed that the form nanoparticles are coarse solid powder and brownish yellow. The TEM image shows an average nanoparticle size of 8.22 nm. Glutaraldehyde crosslinked alginate-chitosan nanoparticles adsorbed paracetamol with adsorption kinetics followed a pseudo-second-order or Ho-McKay model, the adsorption rate constant of 0.0324 g mg−1 min−1. The isotherm study of paracetamol adsorption by glutaraldehyde cross-linked alginate-chitosan nanoparticles followed the isotherm Dubinin-Radushkevich isotherm model with a free energy value of 707.1068 kJ mol−1, and this value indicates the adsorption process by chemically or chemisorption.
