“…According to the obtained results as pH increases, the response surface and removal efciency of Pb (II) increased. Because at high pH, the surface groups of hydroxyl have a negative charge and cause the absorption of cations [40]. Similar results were observed by Zhang et al, Katlego et al, and Wang et al, when they studied the removal of Pb (II) from an aqueous solution by fried egg jellyfsh hydroxyapatite/magnetite composite adsorbent and activated carbon, respectively [37,39,41].…”

Tea waste was used to successfully synthesize magnetic nanoparticles (TWMNPs). In this investigation, Pb (II) was eliminated by tea waste modified with magnetite nanoparticles (TWMNPs) was investigated. To prepare the TWMNPs, FeCl3.6H2O was dissolved in double distilled water (DDW) and 20 g of pulp tea was added slowly and stirred, after 30 min TWMNPs adsorbent were separated through an external magnetic field and washed three times with double distilled water (DDW) and ethanol then dried at 60°C. The FESEM test of TWMNPs shows the particle size in the range of 15–20 nm and spherical/cuboid-shaped crystal structure of Fe3O4 (magnetite). X-ray analysis showed that the main XRD diffraction peaks of TWMNPs are related to Fe3O4, HighScore plus X’Pert software was used to identify the phase in this sample. The specific surface area of the prepared magnetite nanoparticles was 25.2 m2.g−1. The pore volume, maximum pore radius, and VSM of TWMNPs were 14.4 cm3.g−1, 2.3 nm, and 3.37–2.41, respectively. The effects of various parameters, such as contact time, pH, concentration, and adsorbent dosage, were studied. The experimental isotherm data were analyzed using the Langmuir and Freundlich models, and it was found that the removal process followed the Langmuir isotherm and the maximum adsorption capacity calculated by Langmuir fitting was 10.67 mg.g−1. In addition, the adsorption kinetics followed the first-order kinetic model and the value of rate constant was found to be 14.04 × 10−2 min−1. The results showed that increasing the pH level led to a rise in the response level and Pb (II) removal. Also, the trend in Pb (II) removal and response level had an increase with increasing the initial concentration of Pb (II). Increasing contact time from 5 to 20 minutes has a slight effect on Pb (II) removal. Considering the results, TWMNPs could lead to suitable results for the removal of Pb (II) from wastewater containing this metal. And the maximum adsorption capacity was found to be 10.67 mg.g−1.

The effects of various dosages of graphene oxide (GO) on the performance of anammox and the underlying mechanisms are not yet fully understood, necessitating the provision of additional details. In this work, the dosage-dependent impacts of GO on the anammox system were investigated from the perspective of molecular biology analysis. The nitrogen removal efficiency (NRE) continuously increased at 10−100 mg/L GO, and a high nitrogen removal rate (NRR) was obtained at 25 mg/L GO. GO also improved the content of extracellular polymer substance (EPS) and the abundances of hzs and nirS genes. Molecular docking demonstrated that GO had a strong binding with the hydrazine synthase enzyme. Microbial analysis revealed that denitrifying bacteria, such as Denitratisoma and OLB13, were enriched, indicating that the high NRE could be attributed to the synergistic effect between denitrification and anammox processes. The analysis of microbial functions suggested that GO could impact various metabolic activities, such as quorum sensing, extracellular electron transfer, and membrane transport. Above all, this work provided detailed insights into the effects of different GO dosages on the anammox system.

“…In its ionic state (Pb 2+ ), lead is toxic to humans even at very small concentrations [ 4 , 5 ]. This is due to its ability to induce oxidative stress, and biologically replace other essential metals [ 6 ] as well as being an enzyme inhibitor [ 7 ]. When absorbed, Pb 2+ bio-accumulates and is inertly stored in organs such as kidneys, liver and central nervous system [ 8 ].…”
