摘要：

Plasticized PVC membranes incorporating conventional potassium-selective neutral ionophores and a neutral H+-selective chromoionophore have been used as reversible sensing devices for an optical determination of K+ activities in pH-buffered solutions. Dynamic range, reproducibility, response time, and selectivity of the new optode membranes are discussed. With this potassium-selective membrane, the reversible optical determination of total K+ concentration in human blood plasma is available. Results are compared to measurements with ion selective electrodes and flame photometry. © 1990, The Japan Society for Analytical Chemistry. All rights reserved.
