Abstract
Description
Lázeň pro výrobu elektropolymemích elektrod.Bath for production of electro-polymer electrodes.
Oblast technikyTechnical field
Vynález se týká lázně určené pro výrobu polymery pokrytých elektrod, přičemž monomery, ze kterých se polymemí vrstvy na podkladových kovových elektrodách elektropolymerací připravují, jsou nerozpustné ve vodných ani okyselených vodných roztocích.The invention relates to a bath for the production of polymer-coated electrodes, wherein the monomers from which the polymer layers are prepared on the underlying metal electrodes by electropolymerization are insoluble in aqueous or acidified aqueous solutions.
Dosavadní stav technikyBACKGROUND OF THE INVENTION
Výroba elektrod pokrytých elektricky vodivými polymerními gely je prováděna nej častěji z vodných roztoků monomerů nebo z roztoků těchto monomerů v některých organických rozpouštědlech například dichlormetanu, acetonitrilu a dalších. Aby bylo možno elektropolymerací provádět je nutno do těchto rozpouštědel přidávat silné elektrolyty, např. chloristany nebo dusičňany sodné a lithné nebo tetraalkylamonné. Základní nevýhodou těchto solí, především tetraalkylamonných je, že jsou velmi pevně vázány v napolymerovaném povlaku a velmi obtížně se z něho odstraňují. Nevýhodou valné většiny používaných organických rozpouštědel je jejich značná toxicita.The production of electrodes coated with electrically conductive polymer gels is most often performed from aqueous solutions of monomers or from solutions of these monomers in some organic solvents such as dichloromethane, acetonitrile and others. In order to carry out the electropolymerization, strong electrolytes, such as sodium and lithium perchlorate or nitrates or tetraalkylammonium perchlorates or nitrates, must be added to these solvents. The basic disadvantage of these salts, especially tetraalkylammonium, is that they are very tightly bound in the polymerized coating and are very difficult to remove. The disadvantage of the vast majority of organic solvents used is their considerable toxicity.
Podstata vynálezuSUMMARY OF THE INVENTION
Výše uvedené nedostatky odstraňuje lázeň pro výrobu elektropolymemích elektrod sestávájící z roztoku monomem, jež má být elektropolymerován, která , t podle vynálezu obsahuje 0,001 až 10 %hmotn. monomeru, 20 až 99,9 % hmotn.The above drawbacks are overcome by a bath for the production of electro-polymer electrodes consisting of a monomer solution to be electropolymerized, which according to the invention contains 0.001 to 10 wt. % monomer, 20 to 99.9 wt.
kyseliny octové a 0,1 až 20 % hmotn. silné anorganické kyseliny, vybrané ze skupiny tvořené kyselinou sírovou, kyselinou chlorovodíkovou, dusičnou, chloristou nebo fosforečnou. Zbytek do 100 % hmotn. tvoří voda.% acetic acid and 0.1 to 20 wt. strong inorganic acids selected from the group consisting of sulfuric acid, hydrochloric acid, nitric acid, perchloric acid or phosphoric acid. The residue up to 100 wt. water.
Použití lázně pro přípravu a výrobu elektropolymemích elektrod umožňuje, díky vlivu kyseliny octové a sírové, snadné a rychlé rozpuštění jinak ve vodě většinou nerozpustných monomerů a současně obsažená kyselina sírová zprostředkuje vedení elektrického proudu, jež je nezbytné pro probíhající elektrolytický polymerační proces. Výhodou vynálezu je také malá toxicita kyseliny octové a sírové a také nízké výrobní materiálové náklady.The use of a bath for the preparation and production of electro-polymer electrodes allows, due to the influence of acetic and sulfuric acid, easy and rapid dissolution of otherwise water-insoluble monomers and the sulfuric acid present at the same time mediates the electrical current necessary for the electrolytic polymerization process. The advantage of the invention is also low toxicity of acetic and sulfuric acid and also low production material costs.
Příklady provedeníExamples
Funkční vzorek lázně pro přípravu a výrobu elektropolymemích elektrod byl připraven tak, že obsahoval 90% CH3COOH, 9% vody a 1% H2SO4. 5 ml této lázně bylo odměřeno do uzavřené elektrolytické cely vybavené pomocnou velkoplochou Pt-elektrodou, referentní argentchloridovou elektrodou a pracovní drátkovou platinovou elektrodou. Elektrolytická cela byla dále opatřena přívody čištěného dusíku. Výše popsané elektrody byly zapojeny na vstup zařízení pro cyklickou voltamperometrii jak popisuje (Volf R., Shishkanova T., Matějka P., Hamplová M., Král V.: Potenciometric Anion Response of Póly (5,15-bis(2aminophenyl)porphyrin) Electropolymerized Electrodes, Anal. Chim. Acta 381 (2-3), 197-205 (1999).A functional sample bath for the preparation and production of electro-polymer electrodes was prepared containing 90% CH 3 COOH, 9% water and 1% H 2 SO 4 . 5 ml of this bath was measured into a closed electrolytic cell equipped with an auxiliary large-area Pt-electrode, a reference Argentine chloride electrode and a working wire platinum electrode. The electrolysis cell was further provided with purified nitrogen inlets. The above-described electrodes were connected to the input of cyclic voltamperometry devices as described (Volf R., Shishkanova T., Matejka P., Hamplova M., Kral V .: Potentiometric Anion Response of Poles (5,15-bis (2aminophenyl) porphyrin) Electropolymerized Electrodes, Anal Chim Acta 381 (2-3), 197-205 (1999).
Po vybublání vzorku lázně, podle vynálezu, čistým dusíkem, bylo do elektrolytické cely vpraveno malé množství tetra(o-ammofenyl)porfyrinu. Koncentrace této látky v lázni po jejím rozpuštění činila 0,005 mol/1. Metodou cyklování potenciálu [1] mezi potenciálovými mezemi -0,05 a 1,2 V byly pracovní drátkové elektrody pokrývány po dobu 20 min. vrstvičkou polytetra(o3 aminofenyljporfýrinu. O těchto elektrodách je literatuře [1] známo, že jsou značně selektivní k iodidovým iontům. Z toho důvodu bylo 5 ks připravených elektrod testováno v rozsahu koncentrací iodidů 10'1 až 104 mol/1. Proměřením elektrod bylo zjištěno, že se jejich hodnoty Nemstovských směrnic pohybují j v rozsahu 57 až 58,2 mV/koncentrační dekádu. Blíží se tedy teoretické hodnotě.After purging the sample of the bath according to the invention with pure nitrogen, a small amount of tetra (o-aminophenyl) porphyrin was introduced into the electrolysis cell. The concentration of this material in the bath after dissolution was 0.005 mol / l. Using the potential cycling method [1] between potential limits of -0.05 and 1.2 V, the working wire electrodes were covered for 20 min. These electrodes are known in the literature [1] to be highly selective for iodide ions. For this reason, 5 pcs of prepared electrodes were tested over a range of 10 -1 to 10 4 mol / l iodide concentrations. their Nemst Directive values range from 57 to 58.2 mV / decade, thus approaching the theoretical value.
Průmyslová využitelnostIndustrial applicability
Lázeň pro přípravu a výrobu elektropolymerních elektrod, podle vynálezu, nalezne uplatnění ve výzkumných i vývojových chemických a biochemických laboratořích a při hromadné výrobě iontově selektivnívních elektrod, založených na vrstvičkou elektropolymeru pokrytých chemicky indiferentních elektrodách.The bath for the preparation and production of electropolymer electrodes according to the invention will find application in research and development chemical and biochemical laboratories and in mass production of ion-selective electrodes based on electropolymer layer coated with chemically indifferent electrodes.
