| 摘 要： | 运城盐湖卤水中含有大量的有机质和一些无机杂离子,文章通过将盐湖卤水絮凝、活性炭吸附精制后,与硫氢化钡反应,再通过调节溶液pH值降低产品中的硼含量、反应完后利用母液保温沉化降氯离子后,可提高氢氧化镁的质量,使其达到高纯氢氧化镁的要求.

| Abstract: | The brine of Yuncheng salt lake contains a large amount of orgnic matter and a few impurity inorganic ions.We put forward a new method to improve the quality of magnesium hydroxide and meet requiremtns of producing high purity magnesium hydroxide.The steps are as follows:(1)the salt-lake brine was treated via flocculating and adsorbing with active carbon,(2) the solution treated reacted with barium hydrosulfide,(3)the pH value of solution was adjusted to decrease the content of boron in production,(4)the insulating and aging time of mother liquid was controlled to decrease the content of chlorine ion in production. |
