摘要
探讨了差示紫外分光光度法测定高浓度（１％以上）Ｓｂ２Ｏ３－ＥＧ溶液中Ｓｂ２Ｏ３含量的 可行性，结果表明，只要途择合适的参比溶液浓度及测量波长，并使试样的吸光度控制在 ０．２～０．７之间测测定误差就可控制在±０．０１％以内，可以满足聚酯生产分析要求。
The feasibility of determination of Sb2O3 content of hight concentration (above 1%) Sb2O3-EG solution by differential ultraviolet spectrophtometry is discussed. The experimental results proved that, provided suitable reference solution density, suitable wavelengh are taken, and then the absorbance of samples are controled within 0. 2 - 0. 7, the deviations of analysis results can be kept within ± 0.01% to meet the analysis for PET production.
