摘要
研究了氢氧化铈合成的绿色方法.以碳酸铈和醋酸为主要原料,最后获得氢氧化铈和醋酸钠.探讨了过氧化氢的加入方式、过氧化氢的加入量、反应温度、醋酸铈的浓度、氢氧化钠的加入量对铈的氧化率的影响.用扫描电子显微镜对氢氧化铈进行了表征.铈的氧化率大于98%,铈的收率大于99%.
A green method for ceric hydroxide synthesis with cerium carbonate and hydrogen peroxide as main raw materials is reported, and two products, ceric hydroxide and sodium acetate, are obtained. The effects of feeding procedure of hydrogen peroxide, the amount of hydrogen peroxide added, reaction temperature, cerium acetate concentration and sodium hydroxide added on the oxidation of cerium are investigated. Ceric hydroxide is characterized by a scanning electron microscope. The oxidation percentage of cerium is over 98%, and the recovery over 99%.
