摘要：

A PVC membrane sensor for Hg(II) ion based on a sulfur Schiff's base 1-(2-hydroxy-1,2-diphenylethylidene)thiosemicarbazide (HDPET) as ionophore was prepared. The sensor exhibits a Nernstian response for Hg2+ ions over a wide concentration range 1.0 x 10(-2) -2.0 x 10(-6) M. It revealed very good selectivity for Hg2+ over a wide variety of other metal ions and could be used in a pH range of 2.0-5.0.
