摘要

In this work a new Lu3+ PVC-membrane sensor based on 2,2'-dithiobis(4-methylthiazole) (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 x 10(-6)-1.0 x 10(-2) mol L-1 and a detection limit of 6.8 x 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.
