It removes errors of up to 4% in stoichiometric calculations that occur for apatite when an incorrect normalization is used.

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. 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.

Bento Gonc¸alves 9500, 91540-000 Porto Alegre-RS, Brazil The difference between ED and SED is made via the use of monovalent membranes which reject multivalent ions to pass through the membrane. Typically multivalent ions like sulphates, carbonates, phosphates tend to move faster through standard grade membranes than monovalent ions like nitrates. Nanofiber Based Organic Solvent Anion Exchange Membranes for Selective Separation of Monovalent anions Yan Zhao Department of Chemical Engineering, KU Leuven, Celestijnenlaan 200F, B-3001 Leuven, Belgium AEMs that are capable separating univalent/multivalent anions are in urgent need. Generally, AEMs with monovalent selectivity are based on sieving and electrostatic repulsion mechanisms [ 12 ]. The monovalent selectivity is also influenced by membrane surface morphology and membrane surface hydrophilic–hydrophobic property [ 13 ].

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).

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.
