“…The adsorption capacities with the various initial concentrations of the sunset yellow dye (50 and 300 mg/L) for Z1 sample were studied by the adsorption models using Langmuir and Freundlich isotherms. The experimental data are used for the description of adsorption behavior of sunset yellow dye on 0.05 gram of the synthesized Z1 sample at pH=7 and 293 K. The equations of Langmuir, Freundlich and Temkin [16][17][18][19][20] are displayed in No. 3, and 5, respectively.…”

“…The adsorption capacity of zinc aluminum layered double hydroxides sample increased with time and reached to maximum as shown in Figure7(a, b and c). Kinetic factors of the removal sunset yellow dye on Z1 sample were detected using pseudo-first order, pseudosecond-order equations and intraparticle diffusion model [16][17][18][19][20]as shown in the following equations No. 6, 7 and 8.…”

The current research aimed for the preparation of the zinc-aluminium layered double hydroxide by co-precipitation method using metal nitrates and sodium hydroxide. The obtained product was studied using X-ray diffraction, Highresolution transmission electron microscopy, Fourier transform infrared spectroscopy and Field-emission scanning electron microscopy. XRD data appeared that the obtained zinc-aluminium layered double hydroxide is in the range of the nanoparticle. The crystallite and particle sizes were determined from XRD and TEM. The adsorption parameters of organic dye removal using the zinc-aluminium layered double hydroxides were investigated using a batch method. The adsorption isotherms and kinetic models were studied utilizing the synthesized zinc-aluminium layered double hydroxide.

“…Owing to its low cost and efficiency of electron transfer, NGB acts as a mediator in electro catalysis, especially for dopamine and uric acid, and can also be used in several spectrophotometric devices [16]. Naphthol green dye B is dangerous for humans; it may cause health problems such as increased heart rate, shock, and cyanosis [17].…”

Synthetic dyes widely used in many kinds of industry affect the colour of wastewater when released to environment due to insufficient treatment in typical sewage treatment plants. Only a small dose of those dyes may significantly affect colour of water and, according to the chemical composition, may pose risks to wildlife and humans. In the research described in this study, decolorization of three various dyes was investigated. Since colour removal of Congo Red such as Methylene blue using ozone have been reported by several authors, and the literature on Naphthol Green B is rather limited, in the present study we compare the decolorization rate of CR, MB and NGB. The colour removal occurred quickly and more than 90% of colour reduction was achieved within 3-6 minutes throughout all tested pH of the solution.

Over the last few decades, nanotechnologies have gained a great deal of attention, and various nanomaterials and techniques have been developed for water remediation. This study deals with the adsorption of Naphthol green B onto the magnetite nanoparticles synthetized by the coprecipitation method at the laboratory temperature. According to the obtained results, the sorption process is obvious only at the acidic condition when the pH of solution decreases to pH level 3. According to nonlinear fit of experimental data, the sorption of the Naphthol green B onto magnetite nanoparticles is assumed as multilayer, while the Freundlich model fits better (96.158 %) than the Langmuir model does (55.941 %).
