| 摘 要： | 碳酸钡与硫酸钾为原料,采用离子交换法合成硫酸钡,考察了工艺参数对硫酸钡产率的影响,并采用X射线衍射(XRD)、扫描电子显微镜(SEM)、傅里叶变换红外光谱(FTIR)等分析方法对产物晶相、形貌做了表征。结果表明:在c(SO42-)=0.0075 mol/L、液固质量比(g/g)为800∶1、反应温度为30℃、反应时间为72 h的最优条件下,硫酸钡的产率最高可达98.25%,得到的硫酸钡为规则的片状,结晶良好,纯度较高。

| Abstract: | Barium sulfate was synthesized by ion-exchange method,with barium carbonate and potassium sulfate as raw ma-terials.The effects of preparation parameters on the yield of barium sulfate was investigated.X-ray diffraction（XRD）,scan-ning electron microscopy（SEM） and Fourier transform infrared spectroscopy（FTIR） were used to characterize crystalline and morphology.The results showed that the yield of barium sulfate was up to 98.25% under the optimal conditions,such as c（SO4 2-）=0.007 5 mol/L,liquid-solid mass ratio of 800∶1（g/g）,reaction temperature of 30 ℃ and reaction time of 72 h.The obtained barium sulfate was regular flake with crystalline integrity and high purity. |
