0前言 三水县最近发现一个储量巨大的食盐矿,据初步勘探表明,此矿蕴延十八公里,厚层有十多米,最薄的也有三至四米.现采取灌注、溶解、抽取法开采.随机抽出的矿盐水,经化验结果如表1: 表1矿盐水中各组分的含量(mgA) K+ Na+ Ca。+ Mg。+ Mn。+ Fe Ba NH·+ Gd 594.8 106666.66 11 | | |  推荐 CAJ下载  PDF下载 | | | CAJViewer7.0阅读器支持所有CNKI文件格式，AdobeReader仅支持PDF格式 | | | | An Approach to the Reducion of Sulphate Ion Content in Sodium Chloride Mineral Water Solution in Sanshui County | | | Mai Liangmin | | | Sodium chloride mineral water solution is of good quality in Sanshui county. But sulphate ion content in the solution is so high that it has an unfavourable influence over the industry where chlorine and caustic soda are produced . The principles and methods by which SO42- content is lowered and the new way in which SO42- content is determined are discussed mainly in the treatise. The amount of raw material and cost accounted in gravimetric method using CaCl2 as a precipitating agent (termed Calcium method) are compared in detail with those in gravimetric method using BaCl2 as a precipitating agent (termed Barium method). The theoretical calculation and experimental results show that Calcium method is better than Batium method and that SO42- content is determined more quickly and accurately in the new way.
