“…CDs play a significant role in the textile industry, as they can be used to remove surfactants from washed textile materials [31], as leveling agents in dyeing [32][33][34], in textile finishing [35][36][37][38][39], and in wastewater treatment [40][41][42][43].…”

“…The polymer also showed a high adsorptive capacity for MO (602 mg/g) and Congo red (1085 mg/g). Recently, the selective removal of the anionic dye Orange G in a mixture with methylene blue has also been carried out by modifying the TFPN nitriles to form amide groups [41]. An innovative strategy using molecularly imprinted polymers (MPI) from chitosan and β-CD was used for the selective separation of Remazol Red 3BS in a trichromatic mixture.…”

β-Cyclodextrin (β-CD) is an oligosaccharide composed of seven units of D-(+)-glucopyranose joined by α-1,4 bonds, which is obtained from starch. Its singular trunk conical shape organization, with a well-defined cavity, provides an adequate environment for several types of molecules to be included. Complexation changes the properties of the guest molecules and can increase their stability and bioavailability, protecting against degradation, and reducing their volatility. Thanks to its versatility, biocompatibility, and biodegradability, β-CD is widespread in many research and industrial applications. In this review, we summarize the role of β-CD and its derivatives in the textile industry. First, we present some general physicochemical characteristics, followed by its application in the areas of dyeing, finishing, and wastewater treatment. The review covers the role of β-CD as an auxiliary agent in dyeing, and as a matrix for dye adsorption until chemical modifications are applied as a finishing agent. Finally, new perspectives about its use in textiles, such as in smart materials for microbial control, are presented.

“…Today, the permeation of material effluents into the water bodies and biological communities remain a particular problem towards the public wellbeing. Among the various chemical effluents contained in industrial wastewater, synthetic ionic dyes cause environmental issues as it restricts sunlight from reaching aquatic life, greatly decreases the water quality of waterways, introduces poisonous chemicals to food chain organisms and carcinogenic substances that are detrimental to human health (Feng et al 2020;Hameed et al 2017;Kumar 2019;Xu et al 2020). Even at a very low concentration, dyes are easily seen in water bodies which decrease their aesthetic value.…”

“…Due to the increasing demand for products from these industries, the demand for dyes usage is also increased accordingly. Among all the dyes utilizing in industries, textile industries use about 10,000 different dyes, and about 10-15% of dyes used often discharged into the effluent without any adequate treatment (Damasceno et al 2020;Kumar 2019;Xu et al 2020). This means that the wastewater containing dyes must be treated well and met the standards made by the authorities before being discharged.…”

The focal point of this study is to synthesis Alpinia galanga Stem-based activated carbon (AGSAC) by using single-step microwave irradiation and testing it for the removal of cationic dye, methylene blue (MB) from aqueous solution. AGSAC was prepared under the flow of carbon dioxide (CO2) for the gasification effect. The factors of contact time (from 0 to 24 h) and initial concentration (25-300 mg/L) on the adsorption performance of AGSAC were studied. With the aid of response surface methodology (RSM) via face-centered composite design (FCD), optimum preparation conditions for AGSAC were found to be 400 W for radiation power and 4 min for activation time, respectively, which resulted in 95.67% of MB dye removal. The optimized AGSAC has a Bruneaur-Emmet-Teller (BET) surface area of 172.19 m2/g, mesopore surface area of 103.32 m2/g, a total pore volume of 0.1077 cm3/g, and fixed carbon content of 47.63%. The pore diameter of AGSAC was found to be a mesoporous type with a pore diameter of 2.50 nm. Freundlich isotherm and pseudo-second-order were found as the best-fitted model for MB adsorption equilibrium and kinetic respectively onto prepared AGSAC. Intraparticle diffusion was found to be the rate-limiting step.

“…Therefore, after an experimental study of the adsorption process, we examined the LDH applied as a photocatalyst for the MO dye. In this study, we aim to analyze a multiadsorbate system by studying the selectivity of the main dye in the ternary system and then the interaction and behavior of two model cationic dyes (MB and MG) and one model anionic dye, MO [21], with Zn-Fe LDH applied as an effective adsorbent material. The Zn-Fe LDH prepared was well characterized by FT-IR, XRD, FESEM, HRTEM, UV-Vis spectroscopy, N2 adsorption/desorption, zeta potential, partial size analysis, and XPS.…”

Background: In the current work, the removal of cationic and anionic dyes from water was studied both experimentally and computationally. We examine the selectivity of the adsorbent, Zn–Fe layered double hydroxide (LDH) toward three cationic and anionic dyes. Methods: The chemical and physical properties of the prepared adsorbent before and after adsorption were investigated using FT-IR, X-ray diffraction, zeta potential, energy dispersive X-ray, X-ray photoelectron spectroscopy, particle size, HRTEM, and FESEM analysis; optical and electric properties were estimated. The influence of pH on the adsorption process was estimated. Monte Carlo simulations were performed to understand the adsorption mechanism and compute the adsorption energies.Significant Findings: Single dye adsorption tests revealed that Zn–Fe LDH effectively takes up anionic methyl orange (MO) more than the cationic dyes methylene blue (MB) and malachite green (MG). From MO/MB/MG mixture experiments, LDH selectively adsorbed in the following order: MO>MB>MG. The adsorption capacity of a single dye solution was 230.68, 133.29, and 57.34 mg/g for MO, MB, and MG, respectively; for the ternary solution, the adsorption capacity was 217.97, 93.122, and 49.57 mg/g for MO, MB, and MG, respectively. Zn–Fe LDH was also used as a photocatalyst, giving 92.2% and 84.7% degradation at concentrations of 10 and 20 mg/L, respectively.
