Functional copolymers of N-isopropylacrylamide for bioengineering applications

New functional resins with long functional ligands were synthesised by modification of poly(vinylbenzylchloride–acrylonitryle–divinylbenzene) matrix with ethylenediamine, bis(aminopropyl)amine, bis(aminohexyl)triamine or tris(2-aminoethyl)amine. The derivatives were reacted with S -methylthiourea to obtain resins with 2.8–5.0 mmol of amino group per 1 g of dry resin. Sorption efficiency of resin towards Au(III), Pt(IV), Pd(II) chlorocomplexes was determined in a batch mode multicomplexes solutions of Cu(II), Ni(II) and Fe(III) chlorides in 0.1–3 M HCl. The sorption capacity of gold, platinum and palladium from 0.1 M hydrochloric solutions reaches the value of 190, 245 and 280 mg/g, respectively. Recovery of noble metals reveals average of 95% from mulitcomponent solutions.

Sorption of precious metals from acid solutions by functionalised vinylbenzyl chloride–acrylonitryle–divinylbenzene copolymers bearing amino and guanidine ligands

Six porous copolymers of acrylonitrile (AN)/divinylbenzene (DVB) and methacrylonitrile (MAN)/DVB have been synthesised by suspension polymerization in the presence of inert diluents They have different specific surface area (460–720 m 2 /g for AN/DVB and 560–730 m 2 /g for MAN/DVB) and contain various amounts of the strongly polar nitrile groups Their sorptive properties have been studied using dilute (05 mmol) solutions of phenol and its derivatives ( o -chlorophenol, o -, m - and p -nitrophenol, 2,3- and 2,6-dimethylphenol, p -hydroxyphenol) It has been found that sorption of the most hydrophobic compounds and compounds capable of forming strong intramolecular hydrogen bonds does not depend on the polarity of the polymer surface Sorption of phenol and m - and p -nitrophenol is stronger on sorbents having more polar groups The influence of these groups on the sorption process is highly significant in the case of hydrophilic, water soluble sorbates such as p -hydroxyphenol Polymeric sorbents were characterized using elemental analysis, inverse gas chromatography and their porous structure was characterized by nitrogen adsorption at 77 K

Synthesis and chelating properties of resins with methylthiourea, guanylthiourea and dithiocarbamate groups

Immobilization of lipase on various acrylic copolymers

The series of the 4-vinylpyridine and divinylbenzene cationic polymers (4-VP/DVB) in the presence of toluene or toluene and heptane (100 wt.% in respect to the monomers mixture) were synthesised in order to obtain weak base anion exchangers with gel or macroporous structure. The strong base anion exchangers were obtained by its quaternization with alkyl iodide: propyl iodide, butyl iodide and pentyl iodide. The FTIR spectra of anion exchangers were useful to characterize resins and degree of quaternization. The sorption and desorption ability of rhenium, Re(VII), as perrhenate anion from acid solution (sulphuric or hydrochloric acid 0.1 M) were tested in batch and dynamic methods. The sorption of Re(VII) from the solution of 50 mg Re/L reached about 60 mg/g of dry resin in batch method. All the investigated anion exchangers characterize with high selectivity of perrhenate from multicomponent solution containing chlorocomplexes of PGM metals (Pt, Pd) and Au. The sorption ability of PGM metals and Re(VII) is on the same level as from the solution containing only one ion. The dynamic method of sorption allowed to reach the sorption of Re(VII) up 200 mg/g of resin. The desorption of Re(VII) by ammonium (5 wt.%), with the yield about 97%, was possible only from the weak base anion exchangers, where the degree of sorption and desorption is on the same level in the second and other cycles. The sorption ability of Re(VII) on new anion exchanger is comparable to commercial anion exchangers, like Reillex HP.
