“…Subsequently, in the second step, the adsorption rate decreased and the amount (Q t ) retained varied insignificantly from 103.5 up to 104.5 mg/g (Figure 1). Similar studies regarding the influence of contact time on Congo Red dye retention on Amberlite IRA 400 resin have been performed [23]. It was observed that the adsorption of Congo Red at 50 mg/L was achieved quickly, compared with 70 and 100 mg/L concentrations.…”

Despite Acid Blue 113 (AB 113)’s extensive use and negative environmental impact, very few studies have focused on its efficient and environmentally friendly removal. This research aims the removal of AB 113 from environmental aqueous media and its consequent enzymatic biodegradation. A strongly basic anion exchange resin in Cl− form, Amberlite IRA 402 (IRA 402(Cl−)) was used for AB 113 adsorption and a laccase was used to further biodegrade it. For the first time, two novel, efficient and environmentally friendly physical–chemical and biological assays for AB 113 wastewater removal and subsequent biodegradation were combined. The adsorption of AB 113 onto IRA 402(Cl−) was tested in batch and continuous flux modes. Influence of contact time, concentration and desorption in acidic media were evaluated. The kinetic data were best modulated by the Lagergren model with R2 = 0.9275. The Langmuir isotherm model best fitted the experimental data, and the maximum adsorption capacity was 130 mg/g. Dye, resin and AB113 loaded resin were characterized by thermogravimetry and FTIR to evaluate their physical chemical properties modification. Based on the performed studies, a consecutive methodology is proposed, incorporating the ion exchange process in the first stage and the biodegradation process in the second. Thus, in the second stage the residual concentration of AB 113 is reduced by an efficient bio-degradation process produced by the laccase at pH = 4.

“…Fenton reagent is a solution of Fe 2þ /Fe 3þ and hydrogen peroxide (H 2 O 2 ) which can rapidly oxidize diverse organic contaminants by generating highly reactive hydroxyl radicals ( OH) [25]. Among the organic pollutants, azo dyes are of particular concern, as the extensive application of these carcinogenic compounds in different industries has led to their resistance against biological and physicochemical treatments [26,27,28,29,30,31], making the conventional treatment methods ineffective [32]. Various techniques such as hydrothermal [33], sol-gel process [13], chemical co-precipitation [34], template-assisted method [35], thermal decomposition [36], and vapor-solid growth techniques [37] have been exploited for the synthesis of INPs, each suffering from several drawbacks, including a) toxic by-products whose removal requires special treatments, b) high temperature, c) the need for substrate or templates necessitating pre-manufacturing and post-removal difficulties, and d) contaminants which may cause further ecological damages [38,39].…”

Nowadays, green synthesis methods have gained growing attention in nanotechnology owning to their versatile features including high efficiency, cost-effectiveness, and eco-friendliness. Here, the aqueous extract of Chlorophytum comosum leaf was applied for the preparation of iron nanoparticles (INPs) to obtain spherical and amorphous INPs with a particle size below 100 nm as confirmed by TEM. The synthesized INPs managed to eliminate methyl orange (MO) from the aqueous solution. The concentration of MO can be easily checked via ultraviolet-visible (UV-Vis) spectroscopy throughout the usage of INPs at the presence of H 2 O 2 . The synthesized INPs exhibited MO degradation efficiency of 77% after 6 h. Furthermore, the synthesized INPs exhibited antibacterial activity against both Gram-negative and Gram-positive bacteria. The prepared INPs have an impressive effect on Staphylococcus aureus at concentrations below 6 μg/ml. Overall, the synthesized INPs could considerably contribute to our combat against organic dyes and bacteria.

“…Because of their merits of low cost, availability, and ecofriendliness [15], anion-exchange resins such as IRA 402 and IRA-400 have been applied in the aqueous medium for both batch and column adsorption processes. Sinha et al [16] have examined the sorption of the Congo Red (CR) azo dye from aqueous solutions using the Amberlite IRA-400 resin in batch and fixed bed reactors.…”

The removal of brilliant green (BG) dye from an aqueous solution using activated carbon (AC) derived from guava tree wood is conducted in batch conditions. The influence of different factors such as contact time, pH, adsorbent dosage, initial dye concentration, and temperature on the adsorption of BG onto AC was investigated. FTIR, BET, and SEM analyses were performed to determine the characteristics of the material. The isotherm results were analyzed using the Langmuir, Freundlich, Temkin, and Dubinin–Radushkevich isotherms. Linear regression was used to fit the experimental data. It was found that the equilibrium data are best represented by the Freundlich isotherm, and the adsorption capacity (qe) was 90 mg dye/g AC. The values of the free energy (∆G), enthalpy (∆H), and entropy (∆S) were −86.188 kJ/mol, 43.025 kJ/mol, and 128 J/mol.K, respectively, at pH 7 for the BG dye. The kinetics of BG dye adsorption were analyzed using pseudo-first-order and pseudo-second-order models, and it was found that the pseudo-second-order model was suitable for the behavior of the BG dye at R2 = 0.999.
