Ho3+ Ion Selective Microelectrode: An Asymmetric PVC Membrane Sensor

Farnoush Faridbod Mohammad Reza Ganjali Parviz Norouzi

Abstrak

A Ho3+ microelectrode, an asymmetric PVC membrane sensor was prepared based on N-(1-thien-2-ylmethylene)-1,3-benzothiazol-2-amine (TBA) for the first time. TBA shows a good selectivity and sensitivity towards Ho3+ ions, in respect with other tested cations. The log Kf of complexation between Ho3+ and TBA which was calculated by spectroscopic method was 5.23±0.27. The proposed Ho3+ microsensor exhibits a nice Nernstian response of 19.4±0.2 mV/decade of holmium concentration in a wide linear range of 1.0×10-8-1.0×10-3 M and a detection limit of 1.0×10-8 M. It can be used in the pH range of 3.0-8.0.
