“…Ismate violet 2R was chosen as a model compound in this research because of its wide variety of applications, which include dyeing silk, cotton, rayon, leather, paper, wood, and coating for paper stock and medical purposes, as well as its potential harm [ 27 ]. Furthermore, the Ismate violet 2R was classified as a sulfur dye based on their application, which is highly soluble in aqueous solution and has a higher negative charge density, as well as their adsorption preference for various adsorbents [ 28 ].…”

Arthrospira platensis is one of the most important cultured microalgal species in the world. Arthrospira complete dry biomass (ACDB) has been reported as an interesting feedstock for many industries, including biodiesel production. The A. platensis by-product of biodiesel production (lipid-free biomass; LFB) is a source of proteins, functional molecules, and carbohydrates, and can also be reused in several applications. The current study investigated the efficiency of ACDB and LFB in bioremediation of dye (Ismate violet 2R, IV2R) from textile effluents. In addition, the potential of ACDB and LFB loaded by IV2R as a feed for Rotifer, Brachionus plicatilis, was examined. The surface of the adsorbents was characterized by SEM, FTIR, and Raman analysis to understand the adsorption mechanism. The batch sorption method was examined as a function of adsorbent dose (0.02–0.01 g L−1), solution initial concentration (10–100 mg L−1), pH (2–10), and contact time (15–180 min). The kinetic studies and adsorption isotherm models (Freundlich, Langmuir, Tempkin, and Halsey) were used to describe the interaction between dye and adsorbents. The results concluded that the adsorption process increased with increasing ACDB and LFB dose, contact time (120 min), initial IV2R concentration (10 mg L−1), and acidity pH (2 and 6, respectively). For the elimination of industrial textile wastewater, the ACDB and LFB sorbents have good elimination ability of a dye solution by 75.7% and 61.11%, respectively. The kinetic interaction between dye and adsorbents fitted well to Langmuir, Freundlish, and Halsey models for LFB, and Langmuir for ACDB at optimum conditions with R2 > 0.9. In addition, based on the bioassay study, the ACDB and LFB loaded by IV2R up to 0.02 g L−1 may be used as feed for the marine Rotifer B. plicatilis.

“…The group CH-O-PO 2 N is likely to be characterized by the shoulder in the range of 40-46 ppm of the main aliphatic signal (28.7 ppm) [26]. 31 P NMR spectrum confirms that the compound including > CH-O-PO 2 N has a signal at ~0 to 1.4 ppm [27]. Since the mobility of the > CH-O-PO 2 N groups is associated with the polymer via oxygen bridges (Fig.…”

Function modification of polyvinyl alcohol (PVA) having phosphorus-containing heterocyclic compounds is believed to have thermal and biological applications in the area of polymers. The synthesis of phosphorus-containing PVA (P-PVA) was performed using γ-radiation. The chemical structure of the composite polymer is confirmed by spectroscopic techniques of FT-IR, 1H, 13C, and 31P-NMR. Photosensitive properties of polymers were investigated by ultraviolet spectroscopy. Thermal studies are assigned using the Differential Scanning Calorimeter (DSC) and thermogravimetric analysis (TGA). Data display that P-PVA has more thermal stability than PVA. The surface morphology of the prepared hydrogels was performed using scanning electron microscopy (SEM). Quantitative elemental analysis of the P-PVA hydrogel was done through energy-dispersive X-ray spectroscopy (EDX). Antimicrobial activity of the prepared hydrogels using different fungi such as Aspergillus fumigatus, Geotrichum candidum, Candida albicans, and Syncephal-astrum racemosum, in addition to bacteria such as Staphylococcus aureus, Bacillis subtilis (as gram-positive bacteria), Pseudomonas aeruginosa, and Escherichia coli (as gram-negative bacteria), was studied. The phosphorus-contained PVA hydrogels were found to have antimicrobial activity against various fungi and bacteria compared to pure PVA hydrogels.

“…Hydrogels have become more commonly used due to their swelling ability in aqueous media, responsiveness to environmental effects, and biocompatible and biodegradable nature. Hydrogels are the most intensively studied polymeric materials in the literature due to their applications such as drug delivery systems, antimicrobial materials, sensor, pharmacology, matrix materials for tissue engineering, catalyst support material, agriculture, separations and speciation, immobilization, and environmental technologies (34,(36)(37)(38)(39). Anionic hydrogels may be used for absorption and separation of metal ions.…”

In this study, Fe 3+ ion selective N-(Rhodamine-6G)lactam-N'-acryloyl-ethylenediamine (RH6GAC) monomer was synthesized. Then, p(Acrylamide-co-N-(Rhodamine-6G)lactam-N'-acryloyl-ethylenediamine) (p(AAm-co-RH6GAC)) and p(2-hydroxyethylmethacrylate-co-N-(Rhodamine-6G)lactam-N'-acryloyl-ethylenediamine) (p(HEMA-co-RH6GAC)) colorimetric hydrogels were synthesized by using acrylamide (AAm) and 2-hydroxyethylmethacrylate (HEMA) as primary monomers. FT-IR, SEM, polymerization yield and swelling characterizations were conducted for the resulting hydrogels. Then, these hydrogels were used in selective absorption of Fe 3+ ions from aqueous media. The hydrogels, which could absorb Fe 3+ ions selectively from a mixture of metal ions, were used as column packing material. The solutions containing Fe 2+ and Fe 3+ ions at different concentrations were separated at a rate of 97.7 ± 0.7%.
