| NMR Study on the Hydration of Ions in Microemulsion——Bis-2-Ethylhexyl Phosphoric Acid-Alcohol-Kerosine-Water System |

| 摘 要： | In the present investigation we have observed the proton shift of water of hydration of metal ions in a microemulsion formed by adding water gradually front 0.05% to 20% to a moisture-free bis-2-ethflhexyl phosphoric acid-alcohol-kerosine sistem saponified by metallic sodium,so that the mole ratio of concentration (M )/V(H2O) can be varied from 100:1 to 1:100.Under such conditions,we have obtained the lirni's of SME for various cations as follows 6.78PPm(NH4 ),6.80(Li ).5.96(Na ).6.40(K ),in comparison with the proton shift of liquid water,H2O=4.80PPm.

| Abstract: | In the present investigation we have observed the proton shift of water of hydration of metal ions in a microemulsion formed by adding water gradually front 0.05% to 20% to a moisture-free bis-2-ethflhexyl phosphoric acid-alcohol-kerosine sistem saponified by metallic sodium,so that the mole ratio of concentration (M+)/V(H2O) can be varied from 100:1 to 1:100.Under such conditions,we have obtained the lirni's of SMEfor various cations as follows 6.78PPm(NH4+),6.80(Li+).5.96(Na+).6.40(K+),in comparison with the proton shift of liquid water,δ258 H2O=4.80PPm. |
