碱金属离子的纸电泳分离已有不少方法。Alberti等曾用磷酸锆离子交换纸在盐酸介质中电泳分离钾、铷和铯。本文作者考虑到磷钼酸铵作为离子交换剂对碱金属离子具较高的选择性,故将磷钼酸铵固定在滤纸上作成离子交换纸,以硝酸铵和硝酸为电解质溶液对钾、铷和铯的电泳行为进行研究。实验部份一、仪器和试剂可变直流电源,0—300伏,国产。封闭臥式电泳槽(以铂丝作电极),国产。新华牌滤纸。
Alkali metal ion paper electrophoresis separation has many ways. Alberti et al. Used Zirconium phosphate ion exchange paper to separate potassium, rubidium and cesium in hydrochloric acid medium. Taking into account the ammonium phosphomolybdate as an ion exchanger for alkali metal ions with a high selectivity, so the ammonium phosphomolybdate fixed on the filter paper to make ion exchange paper, ammonium nitrate and nitric acid as electrolyte solution of potassium, rubidium And cesium electrophoresis behavior research. Experimental part First, instruments and reagents Variable DC power supply, 0-300 V, made. Closed horizontal electrophoresis tank (platinum wire electrode), made. Xinhua brand filter paper.
