Аннотация:Arylboronic acids are used as novel carriers for membrane electrodes suitable for direct potentiometric determination of the catecholamine drug dobutamine. The carriers are capable of binding diol groups of catecholamines; solvent extraction data confirm the formation of an 1 : 1 complex. For the electrode based on octyloxyphenylboronic acid, the slope of electrode function is S = 58 mV decade(-1); the detection limit is 1.7 . 10(-5) mol/L, the linear range 5 . 10(-4) - 1 . 10(-2) mol/L, the response time 10-20 s. The results suggest the potential use of boronic carriers for the detection of biogenic catecholamines.
