碳酸盐矿物测定钙镁元素,过去是采用分离二氧化硅和三氧化二物后 EDTA 络合滴定,随着水泥事业的飞速发展,石灰石钙镁的分析任务逐渐增大,传统的老方法不能适应生产的需要,近年来分析工作者探索了不少用掩蔽剂掩蔽干扰元素的新方法,并逐步得到改进和完善。不管是碳酸盐矿物,如石灰石钙镁的测定;还是碳酸盐矿物中钙镁的
Carbonate minerals are used to determine calcium and magnesium. In the past, EDTA complexation titration was carried out after the separation of silica and trioxide. With the rapid development of cement industry, the analysis tasks of limestone and calcium magnesium gradually increased. The traditional old method can not In response to the needs of production, analysts in recent years have explored quite a few new methods of masking interfering elements with masking agents and have gradually improved and improved them. Whether carbonate minerals, such as the determination of calcium and magnesium limestone; or carbonate minerals, calcium and magnesium
