摘要: 铬离子敏感半导体器件,简称为Cr6+-ISFET.这种器件是以离子缔合物为活性物质,由于这种材料种类很多,容易制造,并可利用三元络合物来测定高价金属离子,测量一些有机离子,包括表面活性剂,药物、生物碱、浮选药剂和糖精等,这就为离子敏感半导体器件开辟了一个新的应用领域.

Abstract: This paper presents an integrated circuit technique with the aid of Si3N4/SiO2 as the insulator film, and PVC matrix membrane. The Cr6+-ISFET is developed. The test result has shown that Cr6+-ISFET exhibits a linear response to Cr ions within the concentration range of 1×10-2~1×10-5M. The calibration plots have a slope of 56 mV/PCr3F at 25℃. The lower concentration limit of the linear response to Cr (Ⅵ) ions may be 1×10-5M in HF solution.
