The monovalent anion selectivity was determined by the total excess negative charge within the LbL layer, and was largest above 15 layers, since the total excess negative charge was largest above 15 layers. On the other hand, the dominant factor determining the antifouling potential was the hydrophilicity of the membrane surface.

The results suggest that bicarbonate is an essential anion which, together with the other major salivary inorganic monovalent anions, plays an active role in the lysis and ultimate elimination of cariogenic bacteria. PMCID: PMC263338 PMID: 6432696 [PubMed - indexed for MEDLINE] Publication Types: Research Support, U.S. Gov't, P.H.S. MeSH Terms The monovalent permselective anion exchange membranes exhibit high selectivity in removing monovalent anions over di- and multi-valent anions. The transport of sulfate and phosphate through the anion exchange membranes was negligible over a broad range of electrical current density.

Author information: (1)Centro de Investigaciones Biológicas, CSIC, Velázquez 144, E-28006 Madrid, Spain. Thus, Pi is always accepted with a relatively low affinity, and when it participates in exchange, it is always taken as the monovalent anion.

1983-01-04 · Activation of angiotensin converting enzyme by monovalent anions. Bünning P, Riordan JF. The angiotensin converting enzyme catalyzed hydrolysis of furanacryloyl-Phe-Gly-Gly is activated by monovalent anions in the order C1- greater than Br- greater than F- greater than NO3- greater than CH3COO-. A monovalent anion selectivity of 1.43 was obtained subjected to the conditions of 1.0 V operating voltage, together with 10 min adsorption time and 30 mL/min feed flow rate.

A new method is presented for calculating the chemical formula for apatite, and any other mineral that features mixing between halogens and hydroxyl ions on monovalent anion sites, from electron microprobe data that omit H 2 O determination. It removes errors of up to 4% in stoichiometric calculations that occur for apatite when an incorrect normalization is used.

The formula of the salt is written as (NH 4) 2 SO 4. Species with a single charge are univalent (monovalent). For example, the Cs + cation is a univalent or monovalent cation, whereas the Ca 2+ cation is a divalent cation, and the Fe 3+ cation is a trivalent cation. Unlike Cs and Ca, Fe can also exist in other charge states, notably 2+ and 4+, and is thus known as a multivalent (polyvalent) ion.

The transport number ratio between mono- and divalent ions is used to measure the monovalent ion selectivity of the membrane [ 24 , 48 , 49 ]. A new method is presented for calculating the chemical formula for apatite, and any other mineral that features mixing between halogens and hydroxyl ions on monovalent anion sites, from electron microprobe data that omit H 2 O determination. Giant dielectric behavior and electrical properties of monovalent cation/anion (Li +, F −) co‐doped CaCu 3 Ti 4 O 12 ceramics prepared by a solid‐state reaction route were systematically investigated.

The monovalent permselective anion exchange membranes exhibit high selectivity in removing monovalent anions over di- and multi-valent anions. The transport of sulfate and phosphate through the anion exchange membranes was negligible over a broad range of electrical current density.

The blend AIEMs with various mass percent of SPSf show the good miscibility between the two blending components. Simultaneous Analysis of Monovalent Anions and Cations with a Sub-Microliter Dead-Volume Flow-Through Potentiometric Detector for Ion Chromatography. A microliter dead-volume flow-through cell as a potentiometric detector is described in this article for sensitive, selective and simultaneous detection of common monovalent anions and cations in single column ion chromatography for the first time. In general, the selectivity for monovalent anions can be realized through MASM with the mechanisms of: (1) Pore-size sieving effect (the different hydrated ionic radii) (2) Electrostatic repulsion (the difference in electrostatic repulsion between mono-/multi-valent anions) (3) Hydration energy difference (the different Gibbs hydration energy) etc. [5,9] Figure 2 illustrates the possible mechanisms of MASMs in ED process (Cl-/SO The monovalent anion permselectivity of the modified AEMs was evaluated by measuring the relative concentrations of Cl − and SO 42− ions in the dilute compartment.

Hu W(1), Haddad PR, Tanaka K, Sato S, Mori M, Xu Q, Ikedo M, Tanaka S. The main objective of this study is to examine how the charge densities of four monovalent anions—fluoride (F–), chloride (Cl–), bromide (Br–), and nitrate (NO3–)—influence their Donnan (charge) exclusion by a charged nanofiltration (NF) membrane. We systematically studied the rejection behavior of ternary ion solutions containing sodium cation (Na+) and two of the monovalent Separation and extraction of monovalent anions from salt lakes or oceans is very important in view of a sustainable supply of industrial chemical compounds. 2017-08-15 · Monovalent anions selectivity measurement.

The selectivity of monovalent anions was measured in a four compartment module (shown in Fig. S3. in Supporting Information). The current density was 5 mA/cm 2, which is in the suitable range for these membranes. This paper reports that fluorinated PSis with 3,3,3-trifluoropropyl and linear alkyl side chains (F-PSi)s demonstrated monovalent anion size dependent fluorescence quenching, which has potential as a novel type of chemosensor, “monovalent anion indicator”. The extent of the fluorescent quenching was linearly increased by a decrease in the surface charge density of the monovalent anions. In Distribution of a Monovalent Anion in Various Ionic Liquid/Water Biphasic Systems: Relationship of the Distribution Ratio of Picrate Ions with the Aqueous Solubility of Ionic Liquids. Yuta Watanabe; Shoichi Katsuta * A nonintuitive observation of monovalent anion‐induced ion current rectification inversion at polyimidazolium brush (PimB)‐modified nanopipettes is presented. The rectification inversion degree is strongly dependent on the concentration and species of monovalent anions.
