摘要
In this work a new Lu^（3＋） 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（？） 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.
