铝土矿中二氧化碳的含量一般较低。国内外介绍测定铝土矿中二氧化碳的方法甚少,通常是引用其他矿物原料测定二氧化碳的气体体积法,容量法或重量法,其灵敏度或准确度难以达到本标准的要求。如重量法虽有较好的准确度,但测定下限满足不了要求,且繁琐费时。在已见到的同类标准法中,只有苏联列有分析方法(气体体积法)。
Bauxite carbon dioxide content is generally low. Domestic and foreign introduction to the determination of carbon dioxide in bauxite method is very little, usually refers to the determination of other raw materials of carbon dioxide gas volumetric method, volumetric method or gravimetric method, its sensitivity or accuracy is difficult to meet the requirements of this standard. If the gravimetric method has better accuracy, but the lower limit of measurement can not meet the requirements, and cumbersome and time-consuming. Of the similar standard laws that have been seen, only the Soviet Union has an analytical method (gas volumetric method).
