This article considers the development of a new polymeric composition on the basis of polyvinyl pyrrolidone, silver ion solution and benzoic acid for the antimicrobial finishing of cotton fabrics. The advantages of the application of a new composition on the basis of polyvinyl pyrrolidone, silver ion solution and benzoic acid include the availability of the material’s use, as well as the simplicity of the technological process: finishing may be performed with any tenter drier aggregated with a padding machine and combining the drying process and thermal treatment. The newly developed efficient composite formulation for biocidal finishing of cotton fabrics is comparatively inexpensive, environmentally safe, and resistant to wet treatment. Its application offers opportunities of manufacturing of a wide range of competitive, environmentally compatible, and biologically stable cellulose textiles with various textures and various fabric weights. As a result of the study it has been found out that cotton fabrics finished with the composition on the basis of polyvinyl pyrrolidone, silver ion solution and benzoic acid have advanced antimicrobial characteristics preventing fouling with mould fungi and are not deteriorated by microorganisms under operational conditions.

W artykule rozważono opracowanie nowej polimerowej kompozycji opartej na poliwinylo pyrolidonie, roztworze jonów srebra i kwasie benzoesowym w celu uzyskania antymikrobowej preparacji tkanin bawełnianych. Korzyścią zastosowania nowej preparacji jest dostępność składników kompozycji jak i prostota technologicznego procesu nanoszenia za pomocą ogólnie dostępnych urządzeń laboratoryjnych. Opracowana preparacja jest stosunkowo tania, nie stwarza niebezpieczeństwa dla środowiska i jest odporna na mokrą obróbkę. Zastosowanie oferuje możliwości produkcji szerokiego spektrum biologicznie stabilnych, przyjaznych środowisku materiałów celulozowych o różnej strukturze i różnych masach powierzchniowych, impregnowane tkaniny nie ulegają deterioracji przez mikroorganizmy w warunkach normalnego użytkowania.

Polyamide 6.6 multifilaments are grafted with the monomer N-allyliminodiacetic acid for the purpose of removal of some heavy metal ions from their aqueous solutions by forming its metal chelate especially with Ag+ ion. Such a fibrous chelate-forming resin has been used with success due to its large surface area, which contains an important metal chelate-forming functional group, where metal ions are adsorbed or desorbed on its surface, and therefore having an improved adsorption and desorption capability. In previous work, chelate-forming fibre was characterised by ICP-AES analysis according to the digestion method by microwave. The antibacterial activity of the prepared fibre is investigated with Escherichia coli bacteria as reference, according to the zone of inhibition method in agar medium. The material used as reference without metal does not present any effect on E. coli. However, the chelateforming fibres with Ag+ have a strong bactericidal effect, even with a low concentration of silver ions. These modified materials can be used as highly effective bactericidal composites that may be used in future applications for the production of antimicrobial textiles, papers or polymer materials functionalisation

The new diethanethiol-dipyrrolidinyl PNP-lar iat ether, L2, was syn the sized. Spectral properties of the tetrapyrrolidinyl PNP-lar iat ether L1 as well as L2 and their complexes with silver cat ion were investigated. The formation constants of the complexes with Ag+ in methanol solutions were determined. The 1H NMR and potentiometric measurements in dicate that in both cases complexation of Ag+ ions pro ceeds with participation of endocyclic nitrogen atom of cyclophosphazene ring and of polyether oxygen donors. In the case of L2 there is no evidence for stabilization of the ob tained complex by ethanethiol sub units attached to the exocyclic P atom. There is also no evidence for additional stabilization by cyclophosphazene ring or any of the pyrrolidinyl groups.

A novel tripodal thioester type of broom extractant has been synthesized to investigate selectivity for soft metal ions. Broom extractant exhibited high extractability for silver ion compared with monopodal compound. The complexation ratio of the broom extractant and silver ion was found to be 1:1 from the result of extractant concentration dependency. For stripping of loaded silver ion, complete stripping was achieved with both 1 mol dm-3 thiourea and high concentration of acidic solutions. As an application, electrode response of silver ion was observed at concentration range of 10-3 to 10-6 M silver nitrate using broom extractant as an ionophore.
