A new, highly sensitive, and simple sensing method by the use of plasticized PVC film has been developed. The analyte is concentrated on the surface of the transparent film containing 20-30 % of plasticizer such as di-n-octylphthalate (DOP), which serves as a water immiscible second phase for extraction. The resulting film is measured by visual colorimetry or spectrophotometry. Extraction-fluorphotometry can be also adopted for this system. When a colored species is used as the counter ion in the ion-pair extraction colorimetry, marked enhancement of the sensitivity can be realized by the large molar absorptibity of the counter ion and by the color combination of the counter ion, the metal chelate, and the excess reagent, which is effective for discrimination by human eyes. While, adsorption of mono color species, such as the ion-pair of zephiramine (Z^+) and cupper (I) -neocuproin chelate, [CuL_2]^-, on PVC film also offers a high sensitivity without any problem of blank absorption. The detection limit for cupper is 4X10^<-7> mol dm^<-3> by visual colorimetry. The depth profile of the extracted species in the film phase has been investigated. Further, both of the soft PVC containing more than 70 wt% of plasticizer and the solvent without PVC have proved to be useful as new medium for ultra-concentration (3X10^4 hold), separation, and sensing of trace species.

已经开发了一种新的，高度敏感且简单的传感方法，它已经开发出了增塑PVC膜。该分析物集中在透明膜的表面上，该薄膜含有20-30％的增塑剂，例如二核苯甲酸酯（DOP），该甲酸酯（DOP）可作为水不可分化的第二阶段进行提取。通过视觉色彩法或分光光度法测量所得膜。该系统还可以采用提取氟化法。当将有色物种用作离子提取色比色中的反离子时，可以通过对计数器的大摩尔吸收性以及反离子，金属螯合物和过量的试剂的颜色组合来实现灵敏度的明显增强，这对于人眼有效歧视。同时，单色物种的吸附，例如Zephiramine（Z^+）和Cupper（i） - 静脉螯合物的离子对，[CUL_2]^ - 在PVC膜上也提供了高敏感性，而没有任何空白吸收问题。 cupper的检测极限为4x10^<-7> mol dm^<-3>通过视觉色彩法。已经研究了膜相中提取物种的深度谱。此外，事实证明，含有超过70 wt％的增塑剂和没有PVC的溶剂的柔软PVC都可以作为超浓度的新培养基（3x10^4保持），分离和痕量物种的传感。
