摘要
讨论了判断PTA是否受到颗粒污染物的污染及污染程度的方法。用氢氧化铵溶液溶解样品,测定样品的滤膜(0.2μm)和空滤膜的L值,可以判断PTA是否污染及污染程度。
The methods to judgement whether the PTA is polluted by particle pollutant and the pollution degree are discussed.The sample is dissolved by ammonium hydroxide solution.By determination the L value of the measuring sample filter membrane and blank filter membrane,whether the PTA is polluted and the pollution degree can be judged.
