A series of eighteen 4‐vinylpyridine and 4‐methyl‐4′‐vinylbipyridine copolymers with different crosslinkers was examined as sorbents for the noble metal ions of Ag(I), Au(III), Pd(II), and Pt(II) from aqueous solutions. The chelating polymers possess appreciable sorption selectivity for Au(III) over Ag(I) and for Pd(II) over Pt(II). Binding abilities of the copolymers toward the noble metal ions vary as the identity of the chelating heterocyclic amine moiety and the structure of the crosslinkers are altered. © 2001 John Wiley & Sons, Inc.

A phase transfer isocationic substitution of lattice constituent macrocyclic complexes by copper(II) aqua complexes occurs upon the interaction of crystalline mono-and bis(macrocyclic) copper carboxylate complexes with acetonitrile solutions of copper(II) ammine complex. On the other hand, these materials do not react with cupric bis(ethylenediamine).Interest has recently increased in a new class of crystalline materials, namely, organometallic frameworks (OMF). These materials are coordination compounds, in which metal ions are bound to organic ligands [1]. Crystal hydrates are a particular class of OMF consisting of copper(II) and nickel(II) azamacrocyclic complexes and aromatic carboxylates and form a broad range of lattices with cavities and/or channels or laminar structure [2]. As a consequence of these features, such OMF are capable of adsorbing some organic and inorganic molecules either from the gas phase or liquids [2].Alcohols are the most common adsorbates in these studies [3][4][5][6][7]. This activity may be attributed to the hydrophilic nature of the cavity surfaces in the lattices of these OMF and the possibility of forming hydrogen bonds between the interacting components. The similarity of the volume of OMF cavities and the total volume of the adsorbed alcohol molecules such as methanol and ethanol indicates binding of the guests in the adsorbent channels. On the other hand, in the case of phenol, this parameter is not always related to the cavity volume due to the possibility of intercalation of the adsorbate between the adsorbent layers [3,4]. The structural factor, i.e., agreement of the pore size and geometrical parameters of the adsorbate is not a principal requirement in the adsorption of small monohydric alcohols but becomes predominant in interaction with large molecules. Thus, OMF derived from the macrocyclic nickel complex [Ni(cl)(H 2 O) 2 ] 3 (BTC) 2 ·24H 2 O (cl = 1,4,8,11-tetraazacyclotetradecane, cyclam, BTC 3-is the 1,3,5-benzenetricarboxylate anion) efficiently bind D-glucose but do not interact with maltose (glucose dimer) [8].The interaction of such framework materials with metal complex species has been studied much less extensively although we might expect high selectivity in systems of OMF adsorbents and metal complex adsorbates in light of the fit of the geometrical dimensions of the adsorbate and adsorbent pores and the complementary spatial nature of the reagents from the viewpoint of a chemical reaction between them. Furthermore, since the adsorbed metal complexes are in a molecularly dispersed state within the matrix, their subsequent transformations may lead to the formation of hybrid materials containing new types of nanoparticles or clusters in the OMF cavities.0040-5760/07/4302-0131

Dibenzo-18-crown-6 supported on a styrene-divinylbenzene copolymer matrix (PDB18C6) was found to be an efficient sorbent of Pd(II) and Pt(II) from aqueous K 2 PdCl 4 and K 2 PtCl 4 solutions, respectively, because of formation of complex ion pairs where K + was coordinated with the crown ether moiety while the platinides(II) were present in the paired anionic species. Sorption stoichiometry and binding constants determined for the interaction of PDB18C6 with K 2 PdCl 4 and K 2 PtCl 4 were distinctive. On the basis of spectral characteristics (electronic absorption and IR) obtained for the immobilized complexes, Pt(II) was assumed to be sorbed as anion [PtCl 4 ] 2while Pd(II) formed multinuclear species [Pd n Cl 2n+2 ] 2-. Within the complex ion pairs, Pd(II), in contrast with Pt(II), may interact with the aromatic substituents of the immobilized DB18C6.

Goal. Fungicide application fungicides, applied separately and at the background of using inoculum Rhizoactive, on the formation of yielding capacity and some structural parameters of soy crops. According to the set goal, the task was to select the most effective fungicides to fight diseases in the crops, when they are applied separately and at the background of seed inoculation with Rhizoactive. Methods. Field and laboratory. Results. It has been established that the formation of the yielding capacity of soya and indexes of crops structure depends on the fungicides type and their application against the background of using inoculant and without it. It has been proved that the highest productivity of soya crops formed in the variants of the experiment with the application of Impact K, 0.8 l/ ha and Coronet 300 SC КС, 0.8 l/ha against the background of treatment of soya seeds with Rhizoactive. Conclusions. Application of fungicides Akanto Plus 28 KC, 1.0 l/ha, Amistar Extra 280 SC, KC, 0.75 l/ha, Bamper Super 490, KE, 1.5 l/ ha, Impact K, 0.8 l/ha, Koronet 300 SC, KC, 0.5 l/ha in the crops of soy at the background of pre-sowing seed treatment with  inoculum leads to the increase of yielding capacity of crops by 11—15% and improved structure of crops, which is, on the one hand, provided by the improving phytosanitary state of soy crops under the action of fungicides, and on the other hand, by the nutrition of plants at the background of activation of legume inoculum.
