【摘要】 本研究建立了电感耦合等离子体发射光谱法（ICP-OES）测定蒙脱石中钛（Ti）元素含量的检测方法。实验结果表明该方法线性关系良好，相关系数（r）大于0.999；钛元素的检出限和定量限分别为0.0965和0.318 mg·kg^-1；精密度和重复性的相对标准偏差（RSD）分别为0.676%和2.29%，加标回收率为99.69%。以上结果说明该方法检出限低，精密度和准确度高，是检测蒙脱石以及类似矿物样品钛元素的理想分析方法。更多还原

【Abstract】 A detection method for determining titanium in montmorillonite by inductively coupled plasma optical emission spectroscopy（ICP-OES） has been established. The experimental results show that the method has a good linear relationship, and the correlation coefficient（r） is greater than 0.999; The detection limit and quantification limit of titanium element are 0.0965 and 0.318 mg·kg^-1, respectively; The relative standard deviation（RSD） of precision and repeatability were0.676 % and 2.29 %, respectively, and the recovery rate of samples was 99.69 %. The above results indicate that this method has a low detection limit, high precision and accuracy, and is an ideal analytical method for detecting titanium elements in montmorillonite and similar mineral samples.更多还原
