【摘要】 用正电子湮没（PA）方法研究了Na₂[Mo₂O₄（EDTA）]·5H₂O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。更多还原

【Abstract】 The Na2[Mo2O4(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.更多还原
