过氧碳酸钆的制备及表征

用碳酸氢铵、氨水和去离子水配制碳酸氢铵溶液,向其中加入氯化钆溶液,得到碳酸氢铵、氨水和氯化钆的混合溶液,向混合溶液中加入双氧水生成过氧碳酸钆沉淀,用XRD衍射、红外分析、扫描电镜、差热-热重和拉曼光谱对过氧碳酸钆进行了表征。结果表明,制备的过氧碳酸钆属正交晶系,颗粒均匀,稳定性好,形貌由薄片叠成花瓣状。

Preparation and Characterization of Peroxycarbonate Gadolinium

Ammonium bicarbonate solution was prepared with ammonium bicarbonate, ammonium hydroxide and deionized water. Gadolinium chloride solution was added to obtain a mixed solution of ammonium bicarbonate, ammonia hydroxide, and gadolinium chloride, and then hydrogen peroxide was added to the mixed solution to generate precipitate of peroxycarbonate gadolinium. The prepared peroxycarbonate gadolinium was characterized with XRD, infrared analysis, SEM, TG-DSC and Raman spectroscopy. The results show that peroxycarbonate gadolinium belongs to orthorhombic system with uniform particle and morphology of laminated petals.
