this strategy may prove very useful for monovalent ligand-analyte interactions, (poly)anion on conductivity, bio-compatability and general surface properties.

2020-06-01 · Membrane surface resistance (R) and monovalent anion perm-selectivity (P) are two important characteristics for monovalent anion perm-selective membranes to be applied in electrodialysis processes. To be specific, the membrane surface resistance ( R ) can influence the membrane stack resistance directly, to affect the energy consumption of the electrodialysis process further.

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 … 2017-08-15 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. 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.

Finally, 2,5-diaminobenzene sulfonic acid (DSA) was grafted onto PDA layer via Michael addition reaction. The crystalized mixed salts from the zero liquid discharge process are a hazardous threat to the environment. In this study, we developed a novel electrodialysis (SBMED) method by assembling the monovalent selective anion-exchange membrane (MSAEM) into the bipolar membrane electrodialysis (BMED) stack. By taking the advantages of water splitting in the bipolar membrane and high perm monovalent to divalent anions in the feed was beneﬁcial to increase the purity of monoprotic acids. High-purity monoprotic acids in the range of 93.9–96.1% were obtained using this novel SBMED stack for treating simulated seawater.

Abstract. Inner pores of carbon nanotubes combine extremely fast water transport and ion selectivity that could potentially be useful for high-performance water desalination and separation applications. We used dye-quenching halide assays and stopped-flow spectrometry to determine intrinsic permeability of three small monovalent halide anions (chloride, bromide, iodide) and one pseudohalide anion (thiocyanate) through narrow 0.8 nm diameter carbon nanotube porins (CNTPs).

Therefore, it is feasible for SBMED to valorize the mixed salts Fluoride, a small and monovalent anion with high charge density, is highly mobile in certain metal fluorides and this unique property of fluoride ion makes it attractive for applications like fluoride ion–selective electrodes and batteries based on fluoride ion transport. Most of the fluoride conductivity studies were made on single crystals. 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] Monovalent Ion Monovalent ions tend to have lower rejection unless they are retained to maintain electroneutrality with multivalent counter-ions. From: Desalination , 2011 The monovalent anions such as F(-), Cl(-), Br(-), I(-), and NO(3)(-) are essential for its exo-beta-1,4-glucanase activity but have no effect on the activity for xylan, while I(-) higher than 5mM would inhibit the exo-beta-1,4-glucanase activity. The monovalent anions Cl(-) and Br(-) activate its endo-beta-1,4-glucanase activity. 2020-06-01 · Membrane surface resistance (R) and monovalent anion perm-selectivity (P) are two important characteristics for monovalent anion perm-selective membranes to be applied in electrodialysis processes.
