ICP-OES法测定脱硫石膏中的硫酸钙和亚硫酸钙

Determination of CaSO_4 and CaSO_3 in Desulfurized Gypsum with ICP-OES Method

采用电感耦合等离子发射光谱法(ICP-OES)对电厂脱硫石膏中的硫酸钙、亚硫酸钙进行了测定。对仪器的工作参数及分析谱线进行了优化,方法精密度(RSD,n=3)小于5%,回收率为94. 20%～107. 90%。可对脱硫石膏进行简单高效检测,操作简便,分析精度高。

The content of CaS04 and CaSO3 in desulfurized gypsum from power plant was determined by ICP -OES method.The optimum working parameters of the ICP -0ES are adjusted and appropriate characteristic line is selected,the precision less than 5%(RSD,n =3),and the reeovery rate is between 94.20% and 107.90%.The CaSO4 and CaSO3 in desulfurized gypsum can be measured simply,preeisely and effieientIy with this method.
