Metal-organic frameworks (MOFs) with a high surface area and excellent stability are potential candidates for uranium (U) adsorption. Amidoxime (AO) is the most widely used functional group to extract U, which usually introduced into MOFs by two-step post-synthetic methods (PSMs). Herein, MOF UiO-66-NH-(AO) was obtained one-step PSM amidoximation from UiO-66-NH-(CN), synthesized new organic ligand of 2-cyano-terephthalic acid whose morphology octahedron could be well controlled ligand. The...
The self-assembly and pH- thermo-sensitivities properties of hydroxypropyl cellulose-graft-poly(N,N-dimethyl aminoethyl methacrylate) (HPC-g-PDMAEMA) copolymers in aqueous solutions were investigated by transmittance, dynamic light scattering (DLS), 1H NMR spectroscopy. Micelles with different structure can be formed varying either pH value or temperature. At low pH, e.g., 3.0, the HPC backbone copolymer collapse to form core micelles stabilized protonated PDMAEMA side chains on surface upon...
Thermo- and pH-sensitive graft copolymers, hydroxypropylcellulose-graft-poly(4-vinyl pyridine) (HPC-g-P4VP), were synthesized via atom transfer radical polymerization (ATRP) characterized. The thermo- pH-induced micellization stimuli-responsive properties of HPC-g-P4VP copolymers in aqueous solution investigated by transmittance, 1H NMR, dynamic light scattering (DLS), so on. For the micellization, P4VP side chains collapse to form core micelles, HPC backbones stay shell stabilize micelles....
Poly(vinyl alcohol-co-ethylene) (EVOH) nanofibers (NFs) prepared by electrospinning technology were used as matrix material and then functionalized with the amidoxime (AO) group for uranium extraction from seawater (UES). During modification process, acrylonitrile (AN) cografted AN acrylic acid (AA) monomers to obtain EVOH-grafted poly (EVOH-g-PAN) NF EVOH-cografted AA (EVOH-g-PAN-PAA) mats one-step chemically initiated graft polymerization (CIGP). Then, a series of NFs modified into AO...
A novel uranium-imprinted adsorbent (AO-Imp fiber) was prepared by radiation-induced crosslinking of amidoxime-functionalized ultra-high molecular weight polyethylene fiber (AO fiber).
Acrylonitrile and 2-(dimethylamino)ethyl methacrylate were grafted onto ultrahigh molecular weight polyethylene fibers, a series of quaternary ammonium (Q)-functionalized amidoxime (AO)-based fibers including Q-AO AO-Q synthesized. The optimal preparation process was determined. results show that the with grafting chains in inner layer groups outer exhibited best adsorption performance. Enhanced kinetics capacities obtained simulated seawater. In comparison showed higher capacity 29.73 mg/g,...
Stellera chamaejasme is a traditional Chinese medicinal plant with wide range of properties and biological activity. In order to evaluate the phytotoxity of S. chamaejasme, effects aqueous extracts (6.25, 12.5, 25, 50 100 g/L) prepared from roots was studied on seed germination seedling growth of rapeseed (Brassica napus), sesame (Sesamum indicum), wheat (Triticum aestivum) maize (Zea mays). The treatments high concentration extract (50 significantly reduced rate four crops compared control...
ABSTRACT The acylated, B‐ring substituted anthocyanins of Tradescantia pallida (TPA) were extracted from the leaves with acidic water, purified on a Duolite‐861 resin and incorporated into model beverage. beverage was composed citrate‐phosphate buffer at pH values 3.5, 4.5 or 5.5, 15% sucrose. Comparison samples contained cyanidin‐3‐glucoside blackberries commercial sample enocyanin grapes. TPA much more stable than other two, particularly higher as judged by pigment retention tristimulus...
We used solvent−vapor treatment methods to determine nanoscale phase separation and thus tailor the charge mobility of poly(3-hexylthiophene)/fullerene (P3HT/C60) blend films. The nanowires obtained by chloroform vapor are rich in C60, whereas 1,2-dichlorobenzene (DCB) P3HT. treated blends offer far superior hole transport than untreated blends, which is attributed a three-dimensional network containing C60 or P3HT nanowires. Meanwhile, electrically bicontinuous morphology realized...
In order to reduce the risk of early freezing damage cement-based materials in winter construction, lime powder was used improve properties Portland cement–sulphoaluminate cement (PC–CSA) composite system at low temperatures. this study, effects dosage on a PC–CSA blended with two proportions (PC:CSA = 9:1 and 7:3) −10 °C were investigated, mechanisms improvement revealed. The results showed that compressive strength effectively improved, setting time shortened by addition powder. Lime could...
ABSTRACT Tradescantia pallida (syn. Setcreasea purpurea ) contained two major anthocyanins. One was cyanidin‐3,7,3 1 ‐triglucoside with 3 molecules of ferulic acid and an extra terminal glucose. The other pigment similar but without the glucose unit. nonacyl portion indentified by comparison Zebrina pendula. acyl/aglycone acyl/sugar ratios were determined using internal standards response factors HPLC. pigments may have potential as food colorants.
Herein, adsorption, separation, and reduction of Au(III) from its aqueous solution were studied with different amine-type, non-woven fabric (NF) adsorbents fabricated radiation-induced graft polymerization. The exhibited adsorption capacities over a concentration range hydrochloric acid (HCl) 5 mM to M, the diethylamine (DEA)-type adsorbent performed best under all test conditions. DEA-type was inert toward other metal ions, including Cu(II), Pb(II), Ni(II), Zn(II) Li(I), within fixed HCl....
ABSTRACT Acylated B‐ring substituted anthocyanins with a 4 1 ‐keto structure may be of interest as food colorants because at pH values above 4.0 they show an extra absorption band 583 nm. This makes the pigments highly colored >4.0. The also provides simple method analysis based on difference between nm 5.5 and 2.0. Delta E 1% cm for major anthocyanin in Tradescantia pallida was 97.
Owing to many problems of the detriment by large amount organic reagents, high cost and difficulty industrialization, development high-efficiency economical technologies for uranium extraction is an irresistible trend support steady supply nuclear energy. Herein, a novel fibrous adsorbent, named as AO-HPE fibers, was prepared introduction amidoxime groups using green vapor-phase grafting polymerization (VPGP) technology monomer acrylonitrile (AN). Gaseous AN grafted onto ultra molecular...
