Perchlorate Solid-Contact Ion-Selective Electrode Based on Dodecabenzylbambus[6]uril

Dodecabenzylbambus[6]uril (Bn12BU[6]) is an anion receptor that binds the perchlorate ion most tightly (stability constant ~1010 M?1) of all anions due to excellent match between size in relation cavity. This new bambusuril compound was used as ionophore ion-selective membrane (ISM) develop selective electrodes (ISEs) for determination concentration utilizing poly(3,4-ethylenedioxythiophene) (PEDOT) polymer film a solid-contact material. Variation content Bn12BU[6] and tridodecylmethylammonium chloride (TDMACl) plasticized poly(vinyl chloride)-based ISM also tested. All prepared ISEs their analytical performance were characterized by potentiometry, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) chronopotentiometry. The showed rapid response sub-Nernstian slope (~57 mV/decade) during potentiometric measurements solutions range from 10?1 10?6 M simultaneously with high stability sufficient selectivity other common inorganic like bromide, chloride, nitrate sulphate. function ISE further verified analysis real water samples (lake, sea, mineral water), which gave accurate precise results.
