Abstract

The citric acid modification produces an intermediate layer on the AB-17-8:C6H8O7 surface; the layer, on one hand, is firmly secured to the surface owing to the electrostatic coupling between the citrate anion and the positively charged trimethylammonium centers of the anion exchanger surface; on the other hand, it has carbonyl groups with a local negative electron density. The sorption of heavy metals cations occurs through coordination interactions via electrostatic mechanism with local centers of negative electron density, in particular, with the carbonylic oxygen atom.

通过改变阴离子交换剂 AB-17-8 的表面柠檬酸基团,控制其对重金属阳离子的选择性吸附
一方面,由于柠檬酸阴离子与阴离子交换器表面带正电的三甲基铵中心之间的静电耦合作用,该层被牢固地固定在表面上;另一方面,它具有局部负电子密度的羰基。重金属阳离子通过静电机制与局部负电子密度中心,特别是与羰基氧原子发生配位相互作用而被吸附。

期刊介绍: Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
