摘要
普钙生产中废气的主要成分是SiF4 。若直接排入大气 ,将严重污染环境。为治理含氟废气 ,沿用已久的方法是处理成Na2 SiF6,本文提出的方法是处理成MgSiF6,同时也有精碘制成。
The main composition of the waste gas from the production of calcium superphosphate is silicon tetrafluoride(SiF 4).If it is directly sent into the air,the environment could be serious contaminated.This paper suggests a new method in which it is recycled into magnesium fluoride silicate(MgSiF 6)with refined iodine as its by_product.
