    在常温常压下,从近中性的混合铈、镨硝酸盐水溶液中,采用臭氧(或氧气)氧化,制得了红棕色的四价铈镨杂多核氧化物,这种在铈的存在下镨的氧化,拟称为“带同氧化”。通过化学分析,X射线衍射物相分析以及与二氧化锰作用的研究,证明了杂多核氧化物中四价镨的存在。该杂多核氧化物溶于浓硝酸、浓盐酸和冰醋酸中,生成血红色的溶液。通过颜色的变化和紫外可见光谱的研究,考察了四价镨在这些溶液中的稳定性。四价镨在冰醋酸中相当稳定,浓硝酸中一小时内逐渐消失,浓盐酸和硫酸(1:1)中则极不稳定。含四价镨的浓硝酸和冰醋酸溶液的吸收光谱,分别在460nm和440nm处呈现宽带特征吸收峰。通过与不含四价镨的纯铈(Ⅳ)、纯错(Ⅲ)及铈钕混合氧化物等光谱的比较,初步认为这两个特征吸收峰与四价镨的存在有关。
