将紫外-可见分光光度法应用于PTMEG色度的测定,对于色度在70以下的标准溶液,在325～335 nm波长范围内,吸光度与色度呈良好的线性关系,相关系数为0.999 8.样品的测定结果表明,该方法与目视比色法的测定结果吻合,并且精确度比目视比色法有很大提高.

The colority of PTMEG was analyzed by a UV-Vis spectrophotometer. Within the 325～335 nm wavelength range,the absorbance and the chromaticity of standard solutions showed a good linear relationship. The linear corresponding coefficient r was over 0. 999 8. The results showed that spectrophotometry method was consistent with the traditonal visual method and the spectrophotometry had higher accuracy.
