文摘

Membrane treatment effect on the sensitivity of potentiometric sensors was shown. Influence of mechanical, thermal and hydrothermal treatment on membrane properties was investigated. Thermal treatment at RH<100% results in selectivity improvement. Decrease in the membrane water uptake increases the accuracy of organic ampholyte concentration determination.
