| Abstrakt: | A new eco-friendly method for creating an optical sensor membrane specifically designed to detect yttrium ions (Y 3+ ) has been developed. The proposed sensor membrane is fabricated by integrating 4-(2-arsonophenylazo) salicylic acid (APASA), sodium tetraphenylborate (Na-TPB), and tri- n -octyl phosphine oxide (TOPO) into a plasticized poly(vinyl chloride) matrix with dimethyl sebacate (DMS) as the plasticizer. In this sensor membrane, APASA functions dually as an ionophore and a chromoionophore, while TOPO enhances the complexation of Y 3+ ions with APASA. The composition of the sensor membrane has been meticulously optimized to achieve peak performance. The current membrane exhibits a linear dynamic range for Y 3+ ions from 8.0 × 10 -9 to 2.3 × 10 -5 M, with detection and quantification limits of 2.3 × 10 -9 and 7.7 × 10 -9 M, respectively. No interference from other potentially interfering cations and anions was observed in the determination of Y 3+ . The membrane showed strong stability and a swift response time of about 3.0 minutes, with no signs of APASA leaching. This sensor is highly selective for Y 3+ ions and can be renewed by treating it with 0.15 M HNO Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
