在建筑材料中广泛使用石膏模盒因含有磷、氟、有机物等杂质而导致水化时间延长、强度降低等问题.采用标准曲线法对石膏模盒样品中氟和磷的含量进行了测定.
The physical performance of plaster mold box, widely used in building materials, could be weaken as the existence of impurities fluorine, phosphorus and other organics. In this paper, the content of fluorine and phosphorus were determined by using the standard curve method.
