“…Since increasing the pH causes a decline in adsorption due to the formation of Cu(OH) 2 precipitate, although the maximum Cu(II) uptakes were observed at about pH 8 and 10 for carob and grape seeds, respectively, pH 5.5 was chosen for further studies. Similar results were reported by Al-Qodah et al, 15 Nadaroglu et al, 12 and SenthilKumar et al 8 The graph for the Fe 3 O 4 /Ni/Ni x B nanocomposite is different from the others. Cu(II) uptakes remained at the same level for all the pH levels studied.…”

Abstract:A novel adsorbent Fe 3 O 4 /Ni/Ni x B nanocomposite was synthesized and used for the adsorption of copper.Moreover, natural adsorbents carob and grape seeds were used for this purpose. The surfaces and the elemental compositions of the adsorbents were characterized by SEM-EDX. The zero point charges of pH of Fe 3 O 4 /Ni/Ni x B nanocomposite, carob, and grape seeds were found as 8.4, 6.0, and 5.6, respectively. The Langmuir, Freundlich, and Dubinin-Radushkevich isotherm models were used for the identification of the mechanism of the adsorption. The adsorptions of Cu(II) on the three adsorbents were well fitted to the Langmuir isotherm. The maximum adsorption capacities obtained from the Langmuir isotherm were 106.4, 15.6, and 15.9 mg/g for Fe 3 O 4 /Ni/Ni x B nanocomposite, carob, and grape seeds, respectively. The equilibrium data of the isotherm models indicated that the Cu(II) adsorptions were favorable for all the adsorbents. The pseudo-first-order, pseudo-second-order, and Weber-Morris intraparticle diffusion models were used for the validation of the adsorption kinetics. The kinetic data were better fitted to the pseudo-second-order kinetic model for all the adsorbents. Fe 3 O 4 /Ni/Ni x B nanocomposite, carob, and grape seeds are promising adsorbents for the adsorption of Cu(II) from water samples. The removal efficiencies were all about 100%.

“…Aromatic C=C and C=O at 1638 cm −1 correspond to protein amide I; the secondary amine group at 1579 cm −1 corresponds to protein amide II; N-H bending at 1430 cm −1 , -CH 3 bending at 1369 cm −1 , -SO 3 stretching/P=O at 1236 cm −1 , C−O−C groups of polysaccharide at 1101 cm −1 , and C−O−H groups of polysaccharide at 1048 cm −1 and 1050 cm −1 show that it is a Homogalacturonan-type polysaccharide (HG) [48]. All of the peaks indicate the presence of polysaccharides, amino acids, esters, and pectin, as confirmed by previous studies [49][50][51]. However, for the dry algae treated chemically by carbonization or solvent, we noticed a more complicated spectrum, with less intense bands and the appearance of a multitude of absorption bands in the fields of analysis.…”

Ulva lactuca has been used to remove many toxic substances from industrial wastewater. In the present study we tried to optimize the efficiency of U. lactuca as an adsorbent of methylene blue (MB) in aqueous solution. U. lactuca was chemically treated with sulfuric acid (UL-H) and sodium hydroxide (UL-OH) and by a slow pyrolysis process (carbonization process) at high temperature T = 600 °C (UL-T) and compared to the nonactive Ulva (UL-NA) and the water insoluble substance (UL-WIS). Several spectroscopic analyses were carried out to detect the biosorption mechanisms of Ulva to remove MB in solution. The effects of different parameters on the adsorption process were studied, i.e., pH (2–10), mass concentration (1–10 g L−1), and contact time (0–120 min). The results showed that the best adsorption of MB by Ulva was at pH = 8, with 5 g L−1 of biomass at 75 min; the best adsorption capacity was 625.0 mg g−1 for UL-OH, which was able to remove more than 89% of MB compared to UL-T, whose removal rate did not exceed 5%. Fourier-transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM) indicated the presence of oxygenated functional groups with a highly porous surface. The kinetic studies confirmed that the majority of treatments follow the pseudo-second-order type. The mathematical models showed that Langmuir model is favorable to UL-OH, UL-WIS, and UL-NA. According to the experimental results, the primary treatment for U. lactuca is a promising environmentally friendly method and an economical strategy for removing MB from aqueous solution. This method can help address the growing demand for adsorbents used in environmental protection processes and the resultant increase in their price.

“…The negative values of ΔG° for EP adsorbent make the overall process spontaneous. 20 The positive values The ΔS° values were found to be positive which suggests an increase in the randomness at the solid/solution interface during the This further confirmed the endothermic nature of the adsorption process. This research assessed the possibility of using expanded Perlite and natural Moroccan clay as an efficient adsorbent for removing RB from aqueous solution.…”

The main purpose of this study is to guide the effectiveness of Expanded Perlite (EP) and Natural Moroccan Clay (NMC) adsorbents in removing cationic textile dyes from solution. To this end, the batch adsorption experiment explored the adsorption of Rhodamine B (RB) by EP and NMC, and therefore the adsorption was accompanied by UV-Vis spectrophotometry technique in an exceedingly specially sorption cell. The effect of temperature on the adsorption isotherm was also evaluated to examine the adsorption phenomenon. Adsorption kinetics was studied by using three different models i.e. pseudo-first-order, pseudosecond-order and intra-particle diffusion model. The findings of kinetic models reveal that the pseudo-second-order model describes well the adsorption process. The removal of dye by the two adsorbents is favorable in the basic medium. The thermodynamic results show that the adsorption process of RB on both adsorbents is spontaneous and endothermic. The results obtained in this work highlight that NMC is more effective than EP for removing of RB dye.
