摘要
探讨了差示紫外分光光度法测定高浓度 ( 1%以上 )Sb2 O3 EG溶液中Sb2 O3 含量的可行性 ,结果表明 ,只要选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,则测定误差就可控制在± 0 0 1%以内 。
The feasibility of measure the content of Sb\-2O\-3 in high comcentration (up 1 %)solution of Sb\-2O\-3 EG with differential ultraviolet spectrophtometry are discussed.The result shows that the measured deviation was controlled between ± 0.01 % as long as appropriate concentration of reference solution and measurement wavelength are selected,the absorbances of samples are controlled within the limits of 0.2～0.7.It can meet a demand for analysis on PET production.
