电感耦合等离子体发射光谱在磷石膏中磷酸钙物相快速测定中的运用

Application of Inductively Coupled Plasma in Rapid Determination of Calcium Phosphate Phase in Phosphogypsum

磷石膏中磷酸钙物相测定决定其使用用途及配比,利用电感耦合等离子体发射光谱测定磷石膏中磷酸钙物相,方法稳定可靠,所选3件样品各种形态P测定结果精密度均良好,每组测定结果的RSD均小于5%,且其加和同总磷测试结果基本保持一致。

The purpose and proportion of calcium phosphate in phosphogypsum are determined by the phase determination of calcium phosphate in phosphogypsum.The determination method is stable and reliable using the Inductively coupled plasma emission spectrum,the precision of the determination results of all component of phosphorus in 3 samples was suitable,and the RSD of each group was less than 5%,and the addition of each component were basically consistent with total phosphorus.
