摘要
以提取钾和锂之后的苦卤水为原料,脱钙后,加入复合分散剂,在室温20℃～25℃下,采用氨水沉淀镁离子,后经50℃升温陈化1h,制备出纤维状纳米氢氧化镁.通过X射线衍射(XRD)、荧光光谱分析(XRF)、电感耦合等离子体发射光谱(ICP)、扫描电子显微镜(SEM)及透射电子显微镜(TEM)等分析手段对产品氢氧化镁进行了分析和表征.
Fiber - like nano - magnesium hydroxide was prepared from bittern, after extraction of sodium and lithium. The bittern was removed of calcium, precipitate magnesium during 20～30℃ in the presence of complex dispersant ammonia solution, and then aged at 50~C. The product was analyzed and characterized by X-ray diffraction （XRD）, X-ray fluorescence spectrum （XRF） , inductive coupled plasma emission spectrum （ICP）, scanning electron microscope （SEM） and transmission electron microscope （TEM）.
