UV transmittance is a very important index to evaluate the quality of polyester ethylene glycol, and the quality of reference water is a factor that will infuence the testing result of UV transmittance. The distilled waters used in analytical laboratories of Dushanzi Co. were collected and their quality was evaluated and optimized. proposals are presented to guarantee the accuracy in testing the UV transmittance of polyster ethylene glycol.%紫外透光率是衡量聚酯级乙二醇产品质量的一项重要指标.而参比水质是影响乙二醇紫外透光率测定结果的一个重要因素,本文通过一系列条件试验,对独山子公司各级实验室蒸馏水水质情况,进行普查并优化,提出保证乙二醇紫外透光率测试准确性的方法.
