| Abstract: | 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. |
