根据色度学原理应用吸光光度法测定了工业乙酸酐及冰乙酸产品的色度。应用分光光度计 ,建立标准曲线 ,通过测定样品在 3 80 780nm处的透光度 ,计算黄变度 ,查得其相应铂 钴色度号。此方法能准确地反映出样品的真实颜色 ,消除了人为误差 ,提高了分析方法的准确度。适用于日常工业分析、科学研究及仲裁 ,对于目视比色时存在色调干扰的样品测定尤为重要。
According to the principle of colorimetry, the colorimetry of industrial acetic anhydride and glacial acetic acid was measured by spectrophotometry. The application of spectrophotometer, the establishment of a standard curve, by measuring the sample at 8080nm transmittance, calculate the yellowing degree, check the corresponding platinum cobalt color number. This method can accurately reflect the true color of the sample, eliminating human error and improving the accuracy of the analytical method. Suitable for routine industrial analysis, scientific research and arbitration. It is especially important for the determination of samples with color tone interference when visual colorimetric.
