采用红外光谱法测定了精TiCl4中CS2的含量并对测定结果进行了不确定度的评定。红外光谱法测定精TiCl4中CS2含量为6.60±0.082mg · kg －1。对标准储备液的配制、标准溶液的配制、标准曲线校正、样品重复性测定、仪器示值所引起的不确定度分量进行了评定，并计算出合成标准不确定度和扩展不确定度。结果表明，标准系列溶液的配制和标准曲线的拟合是引入不确定度的主要来源，在实验中应特别注意。

The content of CS2in fine TiCl4 were determined by infrared spectrometry and its uncertain‐ty was evaluated. The content of CS2 in fine TiCl4 was 6.60 ± 0.082mg · kg -1. The evaluation results show that the preqaration of standard series solution and the standard curve are the main sources of uncer‐tainty in the experiment.
