The TBP/FeCl3 solvent extraction (SX) system exhibits a high selectivity of lithium over magnesium from magnesium-rich brines, but it suffers the difficulty stripping. addition 2-ethylhexyl phosphonic acid mono-2-ethylhexy ester (P507) as modifier to significantly enhances stripping efficiency by controlling Fe3+ coordination. However, performance other acidic extractants similar P507 has not yet been investigated. In this work, we systematically compared four most commonly used commercial...
In this work, tannic acid (TA)-functionalized carbon nanotubes (CNT@TA) were synthesized by hydrogen bond and π–π stacking interactions. CNT@TA embedded with silver nanoparticles (Ag-CNT@TA) was obtained in situ reducing ammonia ions the pore channels of CNT@TA. Ag-CNT@TA added into polyamide (PA) layer interfacial polymerization to fabricate high-performance nanocomposite reverse osmosis membranes. The results show that functionalized CNTs can be uniformly distributed PA matrix random...
To solve the problem of manganese dissolution, which damages spinel structure LiMn2O4, Li+ extraction performances with persulfate at different temperatures were investigated by chemical analysis, and then XRD, FTIR, XPS analyses used to characterize corresponding mechanism. Results showed that high after treatment three kinds persulfate, lithium ions nearly extracted thoroughly almost no dissolution. Na2S2O8 was considered most suitable for extraction. The extraction/insertion repeated...
In recent decades, the advancements in layer-by-layer (LBL) assembly technology have provoked increasing interest preparation of multilayer polyelectrolyte membranes with excellent performance. current study, a novel nanofiltration (NF) membrane was prepared by pressure-driven polyethylenimine (PEI) and polyacrylicacid (PAA) on porous substrate chemical crosslinking. The effect deposition pressure separation performance studied. surface morphology, hydrophilicity charge property...
This study reports the use of hypotonic osmotic shock as a treatment step to enhance recoveries biofuel-convertible lipids and proteins from lipid-rich saltwater Nannochloropsis gaditana (N. gaditana) slurries (biomass content = ~140 mg biomass / g slurry, total lipid ~600 /g biomass). The was induced through repeated washing microalgal with multiple batches fresh water. Subjecting 2 stages freshwater resulted in measurable damage cell membranes (the uptake membrane permeability marker...
A novel copper ion-selective membrane was prepared by pressure-driven depositing poly(ethyleneimine) (PEI) onto the surface of a polyacrylonitrile (PAN) ultrafiltration (UF) and subsequently modified with molecular imprinting technique. Examination infrared spectroscopy scanning electron microscopy (SEM) confirmed PEI successfully introduced hydrolyzed PAN UF membrane. The increase pH ion solution beneficial to template adsorption on deposited (PEI-PAN) In imprinting, cross-linking time...
Ion-exchange membranes have been widely used in the separation of ionic mixtures or as a barrier some types chemical power source because their selectivity to cations and anions. In this article, novel single-ion selective ion-exchange membrane was fabricated selectively separate copper ion from aqueous media. Polyethylenemine (PEI) deposited onto commercial cation-exchange through an electric-field-enhanced procedure, subsequently modified with imprinting technique. The effects different...
ABSTRACT This study reports the modification of commercial cation‐exchange membrane by layer‐by‐layer adsorption polyethyleneimine and poly(acrylic acid) (PAA) to endow them with monovalent ion selectivity. The chemical morphological changes modified surface were examined ATR‐FTIR SEM, respectively. permselectivity for cations membranes was investigated electrodialysis experiments. effects deposited bilayer number, salt concentration, pH dipping polyelectrolyte solutions on selectivity...
