CHITOSAN -- SORBENT -- GOLD(III)
Аннотация: A novel method for the synthesis of a hetaryl containing chelate amino polymer, namely, N (4(5) imidazolylmethyl)chitosan (IMC), with a degree of substitution up to 0.3 was pro posed. The "synthesis in gel" approach involves direct substitution of the hydroxyl group in 4(5) imidazolylmethanol. The structures of these polymers were confirmed by 1H NMR data. For sorption studies, IMC samples were crosslinked with epichlorohydrin and diglycidyl ethers of ethylene glycol and diethylene glycol. The degrees of swelling and sorption properties of the polymers largely depend on the crosslinking agent and the degree of crosslinking. The sorption capacities of IMC for AuIII, PtIV, and PdII ions are higher than those of the nonmodified polymer. The extraction of noble metal ions from chloride solutions becomes more selective with increasing degree of crosslinking. The sorption capacity of IMC for CoII and NiII ions is higher than those of chitosan and its known N heterocyclic derivatives

CHITOSAN -- PHYSICAL-CHEMICAL PROPERTIES -- PYRIDYL DERIVATIVE
Аннотация: Here we report on the method of synthesis in gel of a new heterocyclic aminopolymer-N-2-(4-pyridyl)ethylchitosan (4-PEC) via direct addition of 4-vinylpyridine to chitosan that yields a derivative with the substitution degree (DS) up to 0.8. The comparison of reactivity, thermal, spectroscopic, and sorption properties of a new derivative and its isomer N-2-(2-pyridyl)ethylchitosan (2-PEC) is presented. 2-PEC has higher sorption capacity and forms more stable chelates with [PdCl4]2- and [PtCl6]2- ions than 4-PEC, but the latter shows higher selectivity to noble metals ions in the presence of Cl- ions. A gradual increase of the sorption capacities and the affinity coefficient for Cu2+ and Ni2+ in the row chitosan<4-PEC<2-PEC was related to the increase of electron donor nitrogen atoms content and chelating properties of 2-PEC. A nearly negligible increase of the 4-PEC sorption capacity for Ag+, as compared to plain chitosan, was suggested to be dependent on the difference in complexation models for 2-PEC and 4-PEC derivatives. The density functional theory (DFT) calculations have shown that the "pendant" model of the complex with Ag(I) is energetically favorable only for 2-PEC derivative, while in cases of chitosan and 4-PEC only "bridge" complexes can be formed that results in lower sorption capacity
