Abstract
The H-1 T-2 images for a transverse slice of a PMAA hydrogel with para magnetic Mn2+ ions under the application of a 3 V DC electric field we re observed as a function of elapsed time by means of 270 MHz H-1 n.m. r. imaging. By using the relationship between the concentration of Mn2 + ions and the H-1 T-2 value of water in the gel obtained by H-1 pulse n.m.r., the H T-2 image was converted to the Mn2+ ion concentration i mage. From these experiments, the spatial distribution of paramagnetic Mn2+ ions in the gel under the application of a 3 V DC electric field was obtained as a function of the elapsed time.
