Cd(II) and Cu(II) ions cause many diseases in humans. Therefore, they should be removed from water sources using simple cost-effective adsorbents. Consequently, sodium magnesium silicate hydroxide/sodium hydrate nanostructures were synthesized functionalized 2,3-dihydroxybenzaldehyde as a novel nanocomposite. Several instruments used to characterize the synthetic products, such an X-ray diffractometer (XRD), Fourier-transform infrared spectrophotometer (FT-IR), N2 adsorption/desorption analyzer, CHN elemental energy-dispersive (EDS), field emission scanning electron microscope (FE-SEM). The functionalization of with led disappearance XRD peaks presence broad peak at 2θ = 32°. In addition, FE-SEM images revealed that consisted spheres, cubes, irregular shapes average grain size 115 nm, nanocomposite spherical conglomerates consisting needle-like shapes. anticipated morphology following resulted on backbones nanostructures. EDS results showed composed O, Na, Mg, Si weight percentages equal 38.59%, 5.95%, 16.60%, 38.86%, respectively. Additionally, was C, N, 55.31%, 2.23%, 30.09%, 6.56%, 2.98%, 12.83%, samples utilized for efficient removal cadmium copper aqueous media ion exchange chelation adsorption procedures, Optimum conditions removing achieved pH, time, temperature 7.5, 80 min, 298 K, maximum uptake capacities toward 89.44 mg/g 155.04 mg/g, respectively, 103.73 177.94 Moreover, processes exothermic, chemical, followed pseudo-second-order model Langmuir equilibrium isotherm model.

Nowadays, brine produced in the Reverse Osmosis (RO) seawater desalination plants is a significant and largely untapped source of critical minerals metals, which usually discharged into seas as wastewater. As front face stage mining process, nanofiltration (NF) membranes can be used to separate stream monovalent multivalent ion-rich streams. Since high separation factors are required RO brine, polyelectrolyte multilayers with Layer-by-Layer (LbL) technique were this study modify commercial polyamide NF improve their performance. Two common polyelectrolytes, poly(diallyldimethylammonium chloride) (PDADMAC) poly(sodium 4-styrenesulfonate) (PSS) coated onto two poly-piperazine (NF270 Desal-5 DL). The effects bilayers number outer layer charge on membranes' performance studied using crossflow filtration setups different membrane sizes find higher monovalent/multivalent factor. DL 5.5 provided highest selectivity for mono/multivalent cations (> 21), average rejection group (about 95.7%) short-term experiments. Another interesting result was increase water permeance after it bLs (indicating more than 20% improvement pure permeance). In addition, stability test brines at 20 bar showed that stable over an extended period (22 hours) even factor 34 97.7% average.
