摘　　要：为了解决钨矿石中不同钨含量的快速、绿色环保和准确测定的技术问题,文章建立了酸溶/碱融-电感耦合等离子体发射光谱(ICP-OES)测定钨矿石中钨含量的方法。该法的线性范围0~20μg/mL,线性方程y=97.856x+9.252 6,相关系数γ=0.999 8;方法的加标回收率96.95%~104.21%;精密度0.83%~2.93%;钨含量测定结果的偏差均小于允许差,准确度满足规范要求。In order to solve the technical problems of rapid,green and accurate determination of different tungsten contents in tungsten ores,an acid dissolution/alkali fusion inductively coupled plasma emission spectrometry(ICP⁃OES)method was established to determine the tungsten content in tungsten ores.The linear range of this method was 0~20μg/mL,linear equation was y=97.856x+9.2526,correlation coefficient wasγ=0.9998;the spiked recovery rate of the method ranges was from 96.95%to 104.21%.The precision was 0.83%~2.93%.The deviation of the tungsten content measurement results is less than the allowable deviation,and the accuracy meets the specification requirements.
