Abstract
Изобретение касаетс создани пластифицированных ПВХ-композиций, содержащих электродоактивный компонент и используемых дл изготовлени мембран ион-селективных электродов, предназначенных дл определени концентрации нитрат-ионов в водных растворах . Изобретение позвол еФ увеличить чувствительность электрода в 500 раз и селективность по-отношению к р ду анионов в 3 - 10 раз за счет того, что композици содержит, мас.%: гексаэтоксициклотрифосфазен 50,0 - 60,0; нитрат тетраалкилфосфони с числом атомов углерода в алкильном радикале 8 - 12 0,1 -1,0; поливинил-, хлорид - остальное. 1 табл. i (Л со сг ел О5The invention concerns the creation of plasticized PVC compositions containing an electrodeactive component and ion-selective electrodes used for the manufacture of membranes for determining the concentration of nitrate ions in aqueous solutions. The invention allowed the EP to increase the sensitivity of the electrode by 500 times and the selectivity with respect to the number of anions by 3 to 10 times due to the fact that the composition contains, in wt%: hexaethoxycyclotriphosphazene 50.0 - 60.0; tetraalkylphosphonium nitrate with the number of carbon atoms in the alkyl radical of 8 - 12 0.1 -1.0; polyvinyl, chloride - the rest. 1 tab. i (L with ate O5
