本发明为一种双极型离子迁移管,其特征在于其双极型结构,由沿轴线分布的离子源、正、负离子引出极、反应区、离子门、漂移区、栅网、正、负离子接收极等构成。待测物被离子源电离产生的正、负产物离子分别被正、负离子引出极引入反应区,在高压电源提供的电场中向迁移管的两极飞行,最终分别被正、负离子接收极接收检测。双极型离子迁移管可以同时反映待测物被离子源电离所产生的正、负产物离子信息,为在单一离子模式下峰位置相同的待测物提供更多的差异性信息,从而提高离子迁移谱对待测物的快速识别与检测能力 ...

本文主要研究了在含有 Ti 离子的氯化物熔盐中氟离子对钛阳极的平衡电极电位及极化曲线的影响.实验分别测定了在低价钛浓度为1.3%、2.54%,3.93%的熔盐中加入 F:Ti=1.5:1的 NaF时,钛阳极的平衡电极电位及极化曲线。实验结果表明:加氟离子于含钛离子的氯化物熔盐中,可降低钛的电极电位值,提高阳极电流密度。在含1.3%低价钛的熔盐中加入 NaF 时,阳极电流密度增加2.3A/cm~2,从而为废钛熔盐电解精炼制取优制钛粉,选择合适的电流密度 ...
