开发了一种新型钠离子图像传感器，该传感器包含CCD型半导体和增塑PVC钠离子选择膜。钠离子浓度在10− 1至10− 5 M范围内，输出电位斜率呈线性。优化膜具有近能斯特响应和高选择性的钠离子。该传感器可快速拍摄钠离子图像，每张图像响应时间为0.2秒，从而可以轻松监测单个Na型阳离子交换树脂珠的离子交换反应。 发现在初始阶段Na+-Ba 2+离子交换比Na+-Ca 2+离子交换快。
A new sodium ion image sensor containing a CCD‐type semiconductor and a plasticized PVC sodium ion selective membrane was developed. The output potential slope was linear for sodium ion concentrations from 10−1to 10−5M. The optimum membrane possessed a near Nernstian response and high selectivity to sodium ions. The sensor can take sodium ion images with a fast response, 0.2 s per image, allowing it to easily monitor the ion‐exchange reactions of a single Na‐type cation‐exchange resin bead. It was found that Na+‐Ba2+ion‐exchange was faster than Na+‐Ca2+ion‐exchange in the initial period.
