Description
Electrochemical properties of membranes containing metal tetraphenylporphyrins (MTPP, where M = Al, Ga, In, Tl) and solvents-plasticizers of different nature were studied to develop membrane ion-selective electrodes. It was ascertained that the type of MTPP metal central atom determines the character of the membrane potential dependence on pH value and anion concentration in the solution studied. For all the membranes selectivity series were determined by the method of separate solutions. It is shown that the change in selectivity constants in the series Al-Ga-In-Tl agrees with the type of chemical bond in MTPP and its strength
Abstract (Russian)
С целью разработки мембранных ионоселективных электродов исследованы электрохимические свойства мембран, содержащих металл-тетрафенилпорфирины (МТРР, где М = Al, Ga, In, Tl) и растворители-пластификаторы различной природы. Установлено, что тип центрального атома металла МТРР определяет характер зависимости потенциала мембраны от величины рН и концентрации аниона в исследуемом растворе. Для всех мембран методом раздельных растворов определены ряды селективности. Показано, что изменение констант селективности в ряду Al-Ga-In-Tl согласуется с типом химической связи в МТРР и ее прочностьюAdditional details
