“…It has been reported that alginate-based adsorbents demonstrated acceptable adsorption aptitudes towards various pollutants comprising heavy metals, toxic organic dyes, pharmaceutical residues, aromatic compounds, and other anions such as nitrates and phosphates. 78,79 As a type of water-soluble biopolymer, alginate possesses plenty of functional hydrophilic OH and COOH groups in its structure, which simplies its physical and chemical reactions. Enormous numbers of modications have been conducted, such as graing, crosslinking, composite formation, and surface functionalization by other active groups to boost the adsorption characteristics of native alginate.…”

“…Adsorption kinetics is an important feature that defines the efficiency of the adsorption process. To clarify the mechanism of diclofenac adsorption onto the studied materials and to identify the model that validates the experimental data, three kinetic models were used: pseudo-first-order kinetic model, and pseudo-second-order kinetic model, and intraparticle diffusion model [ 28 , 33 ].…”

“…This is frequently used for treatment of different diseases, and its large consumption led to its detection in various water resources and wastewater treatment plant effluents [ 24 , 25 ]. This compound generates negative environmental impacts and serious health side-effects, and therefore, the removal of DCF from wastewater and polluted water is imperative [ 26 , 27 , 28 ].…”

The present paper describes a new way of obtaining an efficient adsorbent material by functionalization of Mg3Al layered double hydroxides (LDH) with methyl trialkyl ammonium chloride-ionic liquid (IL) using two methods: ultrasound and cosynthesis. Layered double hydroxides are good solid support for the functionalization with ionic liquids due to their well-ordered structure. The immobilization of the ILs in suitable solid supports combine the advantages of the ILs with the properties of the solid supports bringing more benefits such as use of lower quantity of ILs and avoiding of ILs loss in the aqua phase which overall decrease the treatment costs. In case of ultrasound method of functionalization is assured a uniform distribution of IL on the solid surface, but through immobilization by cosynthesis due to the tunable properties of LDH, is assured an intercalation of the ILs between the LDH layers. This fact was highlighted by the X-ray diffraction (RXD), scanning electron microscopy (SEM) analyses and Fourier-transform infrared (FTIR) spectroscopy of the obtained adsorbent. The added value brought by the functionalization of Mg3Al with the studied IL was underlined by the adsorption studies conducted in the treatment process of water with diclofenac content. Kinetic, thermodynamic, and equilibrium studies were performed. DCF adsorption onto the studied materials correspond to a chemisorption, the pseudo-second-order kinetic model describing the most accurately the experimental data. DCF adsorption onto the studied materials occurs as a heterogeneous process, with the experimental data fitting best with the SIPS isotherm. The sample obtained through cosynthesis developed a maximum adsorption capacity of 648 mg/g.

“…The specific surface area of such material was 32 m 2 /g, and the sorption capacity was 129.24 mg/g and 76.14 mg/g for p-cresol and tylosin, respectively. Shamsudin and co-workers [ 71 ] received alginate–carbon films. S BET was 35 m 2 /g and the adsorption maximum for diclofenac was 29.9 mg/g.…”

In this work, alginate–carbon composites with different active carbon content were synthesized and studied by various techniques. The obtained materials can be used as adsorbents in the processes of removing organic pollutants from water. In this study, the effect of the immobilization of activated carbon in calcium alginate was investigated. Textural properties were determined by measuring low-temperature nitrogen adsorption/desorption isotherms. The largest specific surface area was recorded for ALG_C8 and amounted to 995 m2/g. The morphology of alginate materials was determined on the basis of scanning electron microscopy. The adsorption properties were estimated based on the measurements of equilibrium and adsorption kinetics. The highest sorption capacities were 0.381 and 0.873 mmol/g for ibuprofen and diclofenac, respectively. The generalized Langmuir isotherm was used to analyze the equilibrium data. A number of equations and kinetic models were used to describe the adsorption rate data, including first (FOE) and second (SOE) order kinetic equations, 1,2-mixed-order kinetic equation (MOE), fractal-like MOE equation (f-MOE), multi-exponential equation (m-exp), in addition to diffusion models: intraparticle diffusion model (IDM) and pore diffusion model (PDM). Thermal stability was determined on the basis of data from thermal analysis in an atmosphere of synthetic air.
