Комплексы тетрафенилпорфирина c катионами некоторых металлов как ионофоры анионселективных электродов

Abstract

Tetraphenylporphyrin (TPP) complexes of Ni2*, А Г, VO3* and Sn4* were investigated as ionophores of ion selective electrodes and anion selective electrodes with non-traditional selectivity, which deviates significantly from the classical Hofmeister series, were obtained. It was established that NiTPP1 АlTРР and VOTPP function via neutral carriers mechanism, requiring the incorporation of cationic additive into the membrane to provide complete anion function. SnTPP functions via charged carriers mechanism and the maximum selectivity of membranes based on it is achieved by incorporating the lipophilic anionic additive to the membrane phase.
