“…5(a) revealed that the optimum time for removal of azo dyes from the solution was 30 min, which is remarkably good compared with the reported one. 8,15,29,30 After this time the adsorption of the dye remained constant. It may be deduced from this data that azo dye adsorption was initially rapid, then slowed, and eventually remained constant.…”

“…These dyes contain a highly stable structure and are difficult to degrade by the photolytic process and other bacterial methods. 8 In the textile industry CR is most commonly used as a dyeing agent; it comprises benzene rings, and is extremely hazardous and carcinogenic. 9 MO is an acidic dye that is widely used in the textile and printing industries, and exposure to MO causes vomiting and diarrhea.…”

“…Azo dyes account almost for all the textile dyestuffs produced and have been the most commonly used dyes in textile, paper, food, cosmetics and many other industries 7 . The volume of anionic dyes emitted into the environment was predicted to have grown from 50 000 t to almost 6.9 Mt in recent years 8 …”

BACKGROUND Organic dyes are extremely hazardous waste toxins because they can harm all living organisms as well as the environment. Among them, azo dyes are the most harmful, containing a non‐degradable azo group (NN); these dyes are highly hazardous for both humans and animals, even in low concentration. This research study aims to remove hazardous anionic azo dyes from aqueous solutions by a simple adsorption method using zinc oxide quantum dots (ZnO QDs) synthesized by a facile precipitation method. RESULTS As synthesized, ZnO QDs were characterized by transmittance electron microscopy, atomic force microscopy, X‐ray powder diffraction, Fourier transform infrared spectroscopy, zeta potential and Brunauer–Emmett–Teller. The azo dyes Methyl Orange (MO), Congo Red (CR) and Eriochrome Black‐T (EBT) have been removed actively from an aqueous solution using the high adsorption characteristic of ZnO QDs. The results demonstrated that the adsorbent was efficient even at a low concentration at 0.05 g L−1. The maximum adsorption capacity of ZnO QDs at 27 ± 1 °C was 102.9, 124.3 and 60 mg L−1 for MO, CR and EBT, respectively, and all these results have been observed in just 30 min. A pseudo‐second‐order and Langmuir isotherm model satisfactorily suited the dye adsorption data and, up to three cycles, the ZnO QDs demonstrated outstanding reusability. CONCLUSION ZnO QDs showed not only efficient removal of individual dyes but also simultaneous removal of azo dyes from mixture solution and proved to be an effective, eco‐friendly, low‐cost adsorbent for dye decontamination in wastewater. © 2022 Society of Chemical Industry (SCI).

“…As a result, agricultural solid wastes can be used as an economical and eco-friendly adsorbent, as they are abundant and renewable (Abbas and Ahmed, 2016; Bhatnagar et al , 2015). Many agricultural solid wastes used for the removal of dyes from an aqueous solution such as date stones (Phoenix dactylifera ) (El Messaoudi et al , 2017b), jujube shells ( Ziziphus lotus ) (El Messaoudi et al , 2017a), Clitoria fairchildiana (da Silva et al , 2020), Olive pomace (Rizzi et al , 2017), Leaves of Platanus (Kong et al , 2015), Walnut shell (Uddin and Nasar, 2020), Jojoba residues (Al-Zoubi et al , 2020), Calotropis procera (Kaur and Kaur, 2017), Mandarin Peel (Unugul and Nigiz, 2020), Banana peel (Mondal and Kar, 2018), Eragrostis plana Nees (Filho et al , 2017) and waste of citrus sinesis (Asgher and Bhatti, 2012).…”

Purpose Argan nutshell wood (ANW) has been used in this study as an agricultural solid waste to remove Congo red (CR) from an aqueous solution in single and mixture binary in the presence of methylene blue (MB) or crystal violet (CV). Design/methodology/approach The ANW was characterized by Fourier transform infrared and scanning electron microscope analysis. The effect of ANW dose (8–40 gL−1), contact time (0–180 min), pH of the solution (4–11) and CR dye concentration (100–500 mgL−1) on CR adsorption was studied in batch mode and evaluated by kinetic and isotherm models in a single system. In the binary system, the CR removal was studied from a CR + MB and CR + CV mixture with different percentages of dyes, ranging from 0% to 100%. Findings The pseudo-second-order and the Langmuir models could best describe the CR sorption onto ANW in a single system. In addition, in the case of the binary system, there is the appearance of a synergistic phenomenon between the CR and the other cationic dyes and the CR adsorption capacity increased until 12.24 mg g-1 and 12.06 mg g-1 in the presence of the MB and CV in the mixture, respectively. Practical implications This study demonstrated that ANW prepared can be suggested as an excellent potential adsorbent to remove dyes from wastewaters from single and mixture systems. Originality/value This study is original.

“…Many non-conventional adsorbent materials have been tested for their adsorption capacity to remove pollutants ( Al-Zoubi et al., 2020 ). However, The most promising material used as an alternative cheapest non-conventional adsorbents is clay minerals ( Mustapha et al., 2019 ).…”
