Description
Vynález se týká polymerní membrány selektivní na vápenaté ionty v literatuře popsané ionselektivní elektrody na vápník používají různé typy funkčních membrán. Jsou to především pevné membrány z anorganických krystalů jako CaF£ + ЬаР^ /Farren G.M., Ger. 2101339/ nebo CaWO^ /Velely J.f Jindra J., Czech 163358/ a PVC membrány, které mají jako aktivní složku vápenatou sůl kyseliny oktylfenylfosforěčné /Tjell J.C., Růžička J., Ger.Offen. 2,349299/ nebo/1,1,3,3-tetramethylbutyl/ fenylfosforečné /Cosgrove R.E.,US 3729401/. Čidl^ založená na monokrystalech, nedoznala většího rozšíření zejména pro nízkou selektivitu a neideální odezvy. Podstatnou nevýhodou elektrod, používajících vápenaté soli kyselin alkylfosforečných je značná závislost jejich odezvy na pH, což komplikuje jejich analytické využití. Nedostatky obou typů zmíněných membrán odstraňují membrány s neutrálními nosiči. Řadu necyklických neutrálních ionoforů pro membrány selektivní na vápník popsal Simon se spolupracovníky /Helv. Chim. Acta 58, 1535, /1975/. Určitým nedostatkem sensorů založených na těchto neutrálních nosičích jsou pamětové efekty membrán, které zhoršují jejich odezvu při přechodu od koncentrovanějších ke zředěnéjším roztokům.
Podstata membrány selektivní na vápenaté ionty, která je tvořena pevným filmem plastické hmoty, s výhodou polyvinylchloridu, obsahujícím aktivní neutrální nosič ve zmekčovadle použité plastické hmoty, spočívá podle vynálezu v tom, že aktivním neutrálním nosičem je komplex makrocykliokých polyetherdiamidů obecného vzorce
kde Rp ^2» R3> ^4 jsou H nebo alkyl obsahující 1-4 atomy uhlíku, s výhodou methyl, R^ a značí alkyl s 6 - 10 atomy uhlíku, s výhodou benzyl, přičemž obecné složení komplexu je polyetherdiamid . Ca · 2A* kde A je lipofilní organický anion, s výhodou tetrafenyl nebo tetra(p-chlorfenyl) borátový anion.
Jako změkčovadel lze s výhodou použít takových, která mají dielektrickou konstantu vyšší než 10, jako jsou například nitrované alkylarylethery, s výhodou nitrované fenyl-n-alkylethery, kde alkyl obsahuje v) řetězci více než 6 atomů uhlíku.
Vápníkové elektrody založené na uvedeném komplexu mají výhodu v přesně definovaném složení aktivní komponenty, Lineární odezvě в teoretickým průběhem
-1 -5 2+ v širokém koncentračním rozmezí 10 M - 10 M Ca . Odezva elektrody na aktivitu vápenatých iontů je prakticky okamžitá, bez pamětových efektů. Elektrody vykazují vysokou selektivitu pro vápenaté ionty, zejména vzhledem к iontům Na, Mg, K, Rbv a Ca.
V dalším je vynález blíže objasněn na příkladech provedení.
Příklad 1
К roztokuO,55 g polyetherdiamidů I ( Rp R2, Rp R^ « CH^ t Rp Rg « benzyl) a 0,07 g CaíSClOg v 5 ml methanolu se přidá roztok 0,5 g tetra(p-ohlorofenyl) borkalia v 3 ml methanolu. Vyloučená bílá sraženina se po odsátí překrystaluje z nitromethanu a vysuší při 110° C. Získá se 0,7 g komplexu o b.t. 218 - 220°C.
Jeho složení dle elementární analýzy je 2 polyetherdiamid, Ca . 2(01CgH^)^B Příklad 2 mg komplexu z příkladu 1 se rozpustí v 1 ml o-nitro-fenyl-oktyletheru a smíchá s 10 ml 5% roztoku vysokomolekulárního póly vinyl chloridu v cyklhexanonu. Roztok se nalije na vodorovnou skleněnou desku 7 x 15 cm. Odpařením cyklohexanonu za normální teploty se získá fólie síly cca 0,15 mm. Z této folie se vyřízne kroužek a upevní v elektrodovém tělese. Po nalití vnitřního stndartního roztoku á
se-elektroda zkompletuje -zasunutím svodné-argent-chloridové elektrody. S takto připravenou elektrodou byly naměřeny nesledující selektivní koeficienty log kQaM pro tyto ionty M:
Mg = -3,77; Sr « -0,93; Ba = -2,10; li = -2,44; Na =.-3,73;
K - = -3,66; Rb - -4,09; -Cs « -4,30.
