| 摘 要： | 用正电子湮没(PA)方法研究了Na_2Mo_2O_4(EDTA)]·5H_2O的酸离解过程,证实不同酸浓度下存在两种顺磁离子,这与ESR结果相一致。并根据寿命谱的数据,计算出两种顺磁离子的浓度,表明PA方法与ESR方法相互配合,能较详细研究化学反应动力学过程。

POSITRON ANNIHILATION STUDY OF THE Na_2[Mo_2O_4(EDTA)]·5H_2O DECOMPOSITION |
| |
| Abstract: | The Na2Mo2O4(EDTA)]·5H2O decomposition was investigated in acid medium by positron annihilation ( PA ) method. It shows that there are two paramagnetic ions at different acid concentrations in agreement with ESR results. And the concentration of these ions was calculated from the data of lifetime spectra.. It shows that kinetics of chemical reaction can be studied by using PA and ESR methods together, which are complementary to one another. |
