Received Date: 8 November 2010

In this work a new Lu³⁺ PVC-membrane sensor based on 2,2'-dithiobis(4-methyIthiazole) (TMT) has been fabricated. The sensor exhibits a Nernstian slope of 19.6±0.4 mV decade ^-1 in the concentration range of 1.0×10 ^-6-1.0×10 ^-2 mol L ^-1 and a detection limit of 6.8×10 ^-7 mol L ^-1.It could work well in the pH range of 2.7-9.6. The selectivity of the sensor against a lot of common alkaline, alkaline earth, transition, heavy metals and specially lanthanide ions was very good.
