“…Moreover, ZnFe 2 O 4 @AC was tested with the leaching study to confirm the heterogeneity of the adsorbent in water. If leaching from the surface of carbon nanocomposites occurs, leached adsorption sites can contribute to the interaction with organic dyes 60 . However, after removing ZnFe 2 O 4 @AC from aqueous solution at 30 min, there was no change in removal efficiency of the dyes (MO, AY, RhB).…”

BACKGROUNDWater purification of industrial effluents containing toxic organic dyes by low‐cost biomass‐based adsorbents is not only in accordance with environmental remediation policies, but also reduces total treatment costs. The conversion of Opuntia stricta Haw. biowaste, one of the most harmful invasive plants, into absorbents can lessen the ecological problems caused by this plant species as well as create more value‐added products for water decontamination. We report on the fabrication conditions of O. stricta zinc ferrite (ZnFe2O4)‐loaded activated carbon (ZnFe2O4@AC) for the elimination of two types of dyes including Rhodamine B (RhB), methyl orange (MO) and acid yellow17 (AY), with process optimization based on response surface methodology combined with Box–Behnken design. The optimized ZnFe2O4@AC was structurally characterized by scanning electron microscopy and X‐ray diffraction.RESULTSThe optimal ZnFe2O4@AC was attained at a 1.5 ZnFe2O4:OBC ratio, 5 h carbonization time and 519 °C pyrolysis temperature. In removing RhB, MO and AY by optimized ZnFe2O4@AC, remarkable adsorption capacities (53.34–82.8 mg g−1) were achieved via confirmation tests with very low errors (<2%) and high desirability (>95%). Moreover, kinetic results suggested that the Elovich model was the best description for RhB and AY dye adsorption, whereas MO adsorption by ZnFe2O4@AC followed the pseudo‐second‐order model. The maximum adsorption capacities calculated from the Langmuir equation were determined in the order: AY (82.73 mg g−1) < RhB (125.13 mg g−1) < MO (180.51 mg g−1).CONCLUSIONZnFe2O4@AC derived from O. stricta could be recommended as a high‐efficiency bioadsorbent for the elimination of cationic, anionic and neutral dyes. © 2022 Society of Chemical Industry (SCI).

“…Membrane filtration (MF) technique includes several processes, such as reverse osmosis microfiltration, nanofiltration, and ultrafiltration. But MF processes are suffered from some disadvantages, such as the short-life of the membrane and its high cost [18]. Base on the literature, adsorption technology is widely performed in wastewater treatment because it can eliminate pollutants and discolor dye-water resources.…”

In recent years, the treatment of dye wastewater has attracted more attention because of its harmful impact on the environment. Therefore, dye wastewater should be treated using effective treatment methods, such as adsorption, which is widely employed to remediate many dyes from wastewater. This work studied the use of Laurus Nobilis Leaves (LNL) and sawdust (SD) as low-cost natural adsorbents to remediate reactive blue (RB) dye from synthetic wastewater under the influence of their dosages (0.5-5.5 g) for each, pH (3-9), and contact time (10-190 min). The experimental design, analysis of results, and optimization were conducted using Response Surface Methodology (RSM) based on Box-Behnken method (BBM) and the Minitab-Statistical program. The BET and FT-IR tests have been used to characterize these adsorbents, which show that SD-adsorbent includes more pore volume and surface area than LNL-adsorbent. The adsorption isotherms study revealed that Langmuir isotherm was a more fitted model than Freundlich model. Adsorption kinetic shows that the current adsorption process obeys the pseudo-second order model (R2=0.998) compared to the pseudo-first order model (R2=0.973) and the intraparticle diffusion model (R2=0.915). Thermodynamics study revealed that the present adsorption is endothermic, random irregularity at the solid-liquid, and a spontaneous nature. More than 60% of RB-dye removal efficiency was achieved at the optimal conditions, which were 5.5 g of SD-adsorbent, 0.8 g of LNL-adsorbent, pH 3, and 141 min of the contact time. The core results proved that the interaction effect of using multi-natural adsorbents was significant and cost-effective, providing considerable removal of dye from wastewater.

“…Recently, a tremendous amount of study has been dedicated to the expulsion of effluents containing colors with intrinsic toxicity [6]. Adsorption [7], biodegradation by microorganisms [8], coagulation-flocculation [9], electrochemical methods [10], filtration and membrane separation [11][12][13], liquid-liquid extraction [14], ozonation [15], photocatalytic decolorization [16], and wet air oxidation [17] are some of the dye elimination methods that can be used to decrease the environmental impact.…”

Numerous recent studies have shown that discharging colored wastewater into the environment causes contamination, which has adverse impact due to textile, dyeing, and food industries. The current study presents experimental research on the clathrate hydrate technique used for producing pure water from of wastewater contaminated by dyes. Under constant starting conditions, the clathrate formation for binary (water + refrigerant gas) and ternary (water + refrigerant gas + promotor) systems were studied. The R134a gas was used along with Cyclohexane (2.5 vol%), Tween 80 (100 ppm), and silica gel powder as promotors (100 ppm). Moreover, povidone-iodine (500, 2500, and 5000 ppm) and potassium permanganate (10, 50, and 100 ppm) were used as colored compounds in order to prepare synthetic wastewater (model wastewater). The production of hydrates, which rapidly captured the refrigerant gas molecules in the solid phase, was primarily responsible for the pressure drop. Both povidone-iodine and potassium permanganate have a negligible impact on the hydrate formation rates. It was found that the concentration of povidone-iodine and potassium permanganate in the produced water was decreased.As far as we know, the method of using clathrate hydrate to remove the dyes in water has never been investigated. The results showed that the povidone-iodine removal efficiency ranged between 86% and 92%, and the potassium permanganate removal efficiency ranged between 90% and 95%. The removal efficiency was improved by adding promotors, which increased the dissolved gas quantity and the amount of water hydrates. The maximum removal efficiency was accomplished using silica gel powder and cyclohexane, which are more significant than in pure water and Tween 80. This study demonstrated the viability of the clathrate hydrate technique as a green technology for the treatment of colored wastewater effluents from different industries.
