浅谈岩石矿物中的低含量硅的分析

Analysis on low silicon in rocks and minerals

岩石矿物中的元素含量是科研人员的一个重要课题,其中一种元素硅的含量分析常用动物胶重量法。试验发现硅酸胶体过滤时会穿过滤纸,使低含量硅的测定结果偏低,且操作程序复杂,对试验流程不易控制;若采用硅钼蓝光度法,降低了操作难度,提高了准确性。所以硅钼蓝光度法是分析低含量硅的一种优选方法。

Elements analysis is an important subject of researchers ,the common method of silicon analysis is animal glue gravimetric method. There are some disadvantages including lower result, complicated operating procedures and forward process. However, silicon molybdenum blue photometric method decreased operation difficuhy and improved accuracy. Therefore, silicon molybdenum blue photometric method is the preferred method.
