“…Great attention has been rewarded for developing new methods to remove toxic dyes from polluted water to overcome this severe problem. In this context, several techniques have been developed to remove dyes from an aqueous solution such as photocatalysis, degradation, coagulation, flocculation, hydrogen peroxide, ion exchange, reverse osmosis, membrane filtration, precipitation (Akpomie and Conradie, 2020;El Messaoudi et al, 2021e). Among them, adsorption is considered one of the most effective and widely used methods for the removal of dyes from industrial effluents (Dbik et al, 2014).…”

“…The FTIR spectra of ANW before and after adsorption of CR are shown in Figure 1. The bond at 3,322 cm −1 corresponds to hydroxyl −O–H stretching vibration fond on cellulose hemicelluloses and lignin (El Messaoudi et al , 2021c; Salomón et al , 2020; Shakoor and Nasar, 2019). The small strength band at approximately 2,924 cm −1 is attributed to −C − H stretching (El Messaoudi et al , 2017b; Siengchum et al , 2013) and the bands at 1,718 cm −1 and 1,626 cm −1 represent stretching vibrations of –C = O of esters and acids (Jawad and Abdulhameed, 2020; Surip et al , 2020) and aromatic –C = C (El Messaoudi et al , 2016a), respectively.…”

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.

The purpose of this study was to eliminate phosphate (P) from wastewater using MnFe2O4 nanoparticles. BET, TGA/DTG, FTIR, SEM, TEM, VSM, XRD and EDX/Map analyses were used to determine the MnFe2O4 surface properties. The specific surface area of the adsorbent was 196.56 m2/g and VSM analysis showed that the adsorbent has a ferromagnetic property. The maximum P sorption efficiency using MnFe2O4 (98.52%) was achieved at pH 6, temperature of 55 °C, P concentration of 10 mg/L, time of 60 min, and sorbent dosage of 2.5 g/L, which is a significant value. Also, the thermodynamic study indicated that the P sorption process is spontaneous and endothermic. Moreover, the utmost sorption capacity of P using MnFe2O4 was 39.48 mg/g. Besides, MnFe2O4 can be used for up to 6 reuse cycles with high sorption efficiency (>91%). Also, MnFe2O4 was able to remove phosphate, COD, and BOD5 from municipal wastewater with considerable removal efficiencies of 82.7%, 75.8%, and 77.3%, respectively.
