“…Various formulations of modified composites and various state-of-the-art techniques for the removal of dyes from wastewater have recently been proposed by numerous researchers [ 36 , 37 , 38 ]. Thus, new magnetic nanocomposites based on the Fe 3 O 4 magnetite were successfully obtained by combustion and tested as adsorbents for the removal of anionic dyes such as Acid Yellow 42 and Acid Red 213 from aqueous solutions.…”

“…A comprehensive study was performed to evaluate the use of an organometallic oxide chitosan-4-chloroacetophenone/CeO 2 –CuO–Fe 2 O 3 and chitosan-4-chloroacetophenone/CeO 2 –CuO–Al 2 O 3 nanocomposites for the removal of Red 60 disperse dye (DR) from aqueous solutions. An analysis of the molecular structure of the DR dye adsorbed on the surface of these nanocomposites showed that the adsorption process is related to the van der Waals dispersion force [ 37 ]. Recently, various physicochemical and biological wastewater treatment processes have also been studied with various types of adsorbents, such as commercial activated carbon, metal oxide adsorbents, carbon adsorbents, organometallic frameworks, and polymer adsorbents.…”

The rapid development of industries discharges huge amounts of wastewater that contain surface water. For this reason, we used NiO/polydopamine (NiO/PDA) nanocomposite as an efficient material for the removal of Methyl violet 2B from water. It was synthesized and then characterized by Fourier Transform Infrared (FT-IR) spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) analysis, Transmission Electron Microscopy (TEM), and Brunauer–Emmett–Teller (BET). The EDX analysis confirmed the presence of O, Ni, N, and C. The composite has an average particle size of 18 nm. Its surface area is 110.591 m2/g. It was found that the efficiency of dye removal by adsorption on NiO/PDA exceeded that of bare NiO. The adsorption capacity of NiO and NiO/PDA are 126 and 284 mg/g, respectively. The effects of adsorbent dose, dye concentration, and pH on the removal efficiency were examined. The efficiency increased with increasing the adsorbent dose and pH, but dropped from 85 to 73% within 30 min as the initial dye concentration was increased from 0.984 to 4.92 mg/L. Such a drop in the removal efficiency is due to the blocking of the surface-active sites of NiO/PDA, with the high population of dye molecules derived from the continuous increase in dye concentration. The adsorption results of the dye fitted well with the pseudo-second-order kinetics and Langmuir isotherm. The reusability data showed that NiO/PDA was stable across three adsorption–regeneration cycles, thus it can be considered a good recyclable and efficient adsorbent. Because of these results, it can be considered that this method can be applied for the treatment of wastewater.

“…The pattern presented in Figure 8 a suggests that the increasing MV concentration tends to reduce the removal efficiency of either adsorption or photooxidation by both Zn-Al LDHs and c-Zn-Al LDHs. In general, the intensive adsorption was achieved at low concentrations as the rapid removal was higher at an enormous number of available active adsorption spots on the material’s surface [ 31 ]. In more detail, the removal of around 90–100% was achieved at the initial concentration of 1–5 ppm over the photocatalysis process.…”

Zn-Al Layered Double Hydroxides (Zn-Al LDHs) and its calcined form were successfully prepared and utilized for the removal of methyl violet (MV) and treatment of peat water by photocatalytic oxidation. The research was aimed to evaluate the effect of calcination to Zn-Al LDHs for the effect on the physicochemical character and the capability as a photocatalyst. The characterization of the samples was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer–Emmet–Teller specific surface area (BET), and X-ray photoelectron spectroscopy (XPS). The results showed that the increased BET specific surface area along with the enhanced porous structure was achieved by the calcination procedure, which is associated with the enhanced interlayer space of d003 identified by XRD analysis. Thermal conversion showed an influence to the increased band gap energy from 3.10 eV in the uncalcined Zn-Al LDHs into 3.16 eV for the calcined material. These character changes contributed to the enhanced photocatalytic activity of the Zn-AL LDHs by calcination, which was proposed and verified by experiments. It was observed that photocatalytic activity of the material for MV gave about a 45.57% removal of MV and a 68% removal for the natural organic material of the peat water.

“…model is the model that judges the MB adsorption process. At 25 °C, the R 2 calculated by the Langmuir isotherms was 0.9878 For Langmuir adsorption isotherm, the R L value is less than one, meaning that MB adsorption is favourable under the current studied circumstances [70]. According to Langmuir adsorption isotherm, 53.4 mg/g is the maximum expected AC500/NZ's adsorption capacity.…”

Activated carbon/natural zeolite (AC/NZ) was introduced as an effective and stable adsorbent for the enhancement of the adsorption of methylene blue (MB). The activated carbons (ACs) were prepared from sugarcane waste by calcination at different temperatures from 500 to 900 °C. The samples were characterized for confirming their structure and chemical composition by using many techniques. For activated carbon calcinated at 500 °C (AC500), the XRD patterns showed many broad peaks which confirm the amorphous phase of carbonization with disordered micro-graphite stacking. The SEM images of the AC500/NZ nanocomposite show that the zeolite surface is covert with the AC500 particles. The AC500/NZ nanocomposite showed light absorption capability in the visible region than activated carbon only. Batch experiments were performed to study the influence of various practical variables on adsorption processes. Dye adsorption isotherms and kinetics were also investigated. The effect of contact time, starting MB concentration, and pH were all measured. Adsorption of MB was reached to maximum removal (99.2 %) using 50 mg of AC500/NZ after 45 minutes. About 51 mg/g was found to be the maximum AC500/NZ adsorption capacity for MB dye with an initial concentration of 30 ppm, at 25 °C, pH 7, and an AC500/NZ mass of 50 mg. According to the kinetic tests, the best kinetic model for MB adsorption was pseudo-second-order. The adsorption isotherm of dye onto AC500/NZ almost agreed with the Temkin isotherm model. Adsorbed heat energy B value calculated according to Temkin model was less than 1.0 kcal/mol which indicates that the adsorption reaction of MB onto AC500/NZ occurs physically in the concentration studied. Additionally, the adsorption mechanism was also evaluated using Weber's intra-particle diffusion module. Finally, AC500/NZ adsorbent considers a good candidate for water remediation. Monte Carlo (MC) simulation studies indicated the adsorption of MB molecule on the AC/NZ nanocomposite surface in dry system (no solvent) following a parallel mode in most of all studied configurations, confirming the strong interactions between the MB molecule and surfaces atoms of AC/NZ nanocomposite. The molecular structure analysis of MB molecule on the AC/NZ nanocomposite surface indicated that the adsorption process related to Van der Waals dispersion force. Consequently, this helps to trap MB molecule on the AC/NZ nanocomposite surface (i.e., physical adsorption), which supports our experimental results.
