The improvement of heavy metals removal by wood membrane in drinking water treatment: Comparison with polymer membrane and associated mechanism

Improvement of hybrid polyvinyl chloride/dapsone membrane using synthesized silver nanoparticles for the efficient removal of heavy metals, microorganisms, and phosphate and nitrate compounds from polluted water

“…Adsorption isotherms are used to represent the distribution of adsorbate molecules between the liquid and solid phases at the equilibrium of the adsorption process. 39 The adsorption data were analyzed using four adsorption isotherms: the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) models (eqn (1)- (7) and Table S1 †). To explore the adsorption process of the selected elements (Fe 3+ , Mn 2+ , Ni 2+ , Pb 2+ , NO 3 − , PO 4…”

“…5,6 To tackle these shortcomings, nanomembrane-based smart polymeric matrices have been developed to enhance the removal of heavy metals from water resources and provide safe water owing to innovative nanomembranes for living on a healthy planet. Huge efforts [7][8][9] have been made to explore these membranes as viable and cost-effective nanomembrane manufacturing. Regarding renal diseases, the kidney is considered the rst attack organ by heavy metal toxicity that causes acute renal failure, leading mostly to death.…”

Research Advances in Wood Composites in Applications of Industrial Wastewater Purification and Solar-Driven Seawater Desalination

“…Raman spectroscopy and energy spectrum images confirmed –COOH was mostly located on the wood cell walls. Liu et al [ 27 ] compared a wood membrane with a pore size of several tens of microns (μm) with a polymer membrane with a pore size of 0.45 μm. Compared with the polymer membrane with a cobweb structure, the removal efficiency of the wood membrane towards Fe 3+ , Cu 2+ and Mn 2+ by gravity-driven filtration was improved.…”
