In the paper, it is studied the preparation of cerium hydroxide with cerium chloride solution as raw material as well as investigated the concentration of cerium chloride solution, quantity of H2O2 added, amount of NH3·H2O and the effects of reaction temperature on oxidation rate of cerium in cerium hydroxide to determine the optimum technological conditions. The results showed that the cerium hydroxide with oxidation rate of cerium greater than 97%, w(Cl-)<0.15% and could be dissolved in HNO3 solution was obtained when the mass concentration of cerium chloride was 120 g/L, amount of H2O2 was 0.7 times of mass of CeO2, amount of NH3·H2O was 130% of theoretical mass and reaction temperature was at 50 ℃.

研究了用氯化铈溶液为原料制备氢氧化铈,考察了氯化铈溶液浓度、H2O2加入量、NH3·H2O用量及反应温度对氢氧化铈中铈氧化率的影响,确定最优工艺条件。结果表明:在氯化铈质量浓度120 g/L、H2O2用量为CeO2质量的0.7倍、NH3·H2O用量为理论量130%、反应温度50 ℃条件下,得到铈氧化率大于97%,w(Cl-)<0.15%的氢氧化铈,且在常温下能溶于HNO3溶液。

研究了用氯化铈溶液为原料制备氢氧化铈,考察了氯化铈溶液浓度、H2O2加入量、NH3·H2O用量及反应温度对氢氧化铈中铈氧化率的影响,确定最优工艺条件。结果表明:在氯化铈质量浓度120 g/L、H2O2用量为CeO2质量的0.7倍、NH3·H2O用量为理论量130%、反应温度50 ℃条件下,得到铈氧化率大于97%,w(Cl-)<0.15%的氢氧化铈,且在常温下能溶于HNO3溶液。

In the paper, it is studied the preparation of cerium hydroxide with cerium chloride solution as raw material as well as investigated the concentration of cerium chloride solution, quantity of H2O2 added, amount of NH3·H2O and the effects of reaction temperature on oxidation rate of cerium in cerium hydroxide to determine the optimum technological conditions. The results showed that the cerium hydroxide with oxidation rate of cerium greater than 97%, w(Cl-)<0.15% and could be dissolved in HNO3 solution was obtained when the mass concentration of cerium chloride was 120 g/L, amount of H2O2 was 0.7 times of mass of CeO2, amount of NH3·H2O was 130% of theoretical mass and reaction temperature was at 50 ℃.
