Learn faster with spaced repetition. Monovalent Anion Selectivity Permselectivity is a reference indicating the transport of monovalent and multivalent anions through the membrane. Cl − and SO 4 2− were chosen as target anions in the diluted compartment and the permselectivity was calculated and shown in Figure 8 . 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. The results in this study are capable of helping develop the PSMCDI (permselective exchange membrane capacitive deionization) technology and expand its application for the removal of fluoride from drinking water. When the cation and/or the anion is a polyatomic ion, parentheses may be used to group the atoms in the ion together to write the formula. For example, the salt ammonium sulfate consists of the cation NH 4 + and the sulfate anion SO 4 2-.

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.

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. By contrast, when the high-affinity organic phosphates are used, these same systems fail to discriminate between monovalent and divalent forms. 2020-02-21 · The sodium iodide symporter (NIS) transports iodide, which is necessary for thyroid hormone production. NIS also transports other monovalent anions such as tetrafluoroborate (BF4-), pertechnetate (TcO4-), and thiocyanate (SCN-), and is competitively inhibited by perchlorate (ClO4-). However, the mechanisms of substrate selectivity and inhibitor sensitivity are poorly understood.

Burr 50022 monovalent. To simplify the system, all constituent ions are regarded to be only monovalent because almost all ILs are composed of monovalent cations and monovalent anions: [1] σ i = ∑ n j e μ j The terms n j , e , and μ j are the number of j th ions in the material, the charge of an electron, and the mobility of j th ions, respectively.
