【摘要】 通过粉末X-射线衍射分析（XRD）鉴定二氧化钛材料的晶型结构,同时对防鸟鞭样品采用微波消解的方式进行处理,电感耦合等离子体发射光谱法（ICP-AES）来测定二氧化钛的含量。方法确定钛的检测波长为336.121nm,钛的质量浓度在0.1²5mg·L^-1范围内,标准液质量浓度与发射强度呈良好的线性关系,线性方程为y=18180x+638.65（R²=1.000）,钛的检出限为0.003mg·L^-1,精密度（RSD,n=8）为0.365%。该方法简单快捷,数据准确可靠,适合于防鸟鞭中二氧化钛的分析。更多还原

【Abstract】 Through the X-ray diffraction analysis（ XRD） identify the crystal structure characterization of titanium dioxide material. The method for the determination of titanium dioxide by inductively coupled plasma atomic emission spectrometry（ ICP-AES）with microwave digestion. Method to determine the titanium detection wavelength was 336. 121 nm. A good linear relationship was exhibited with the mass concentration of Ti at the range of 0. 1-25mg·L^-1,linear equation y = 18180x+638. 65（ R2= 1. 000）,the detection limit of titanium was 0. 003mg·L^-1,the relative standard deviation（ RSD,n= 8） was 0. 365%. The method is simple and fast,high accuracy,suitable to analysis of the content of titanium dioxide in anti bird whip.更多还原
