| 摘 要： | GB/T7573—2009已经正式实施了。新标准中除三级水以外增加了0.1mol/L氯化钾(KCl)溶液作为萃取介质。针对萃取介质的选择问题,本文用三级水和KCl溶液对多种面料的pH值测试做了比对试验,结果表明:在测试接近中性和偏碱性的溶液时,以KCl溶液为萃取液测定织物的pH值可以提高该范围内pH值测试的稳定性和快速性。

| Abstract: | GB/T 7573—2009 has been implemented.In the new standard,0.1mol/L KCl solution was adding as the extraction medium in addition to 3rd grade water.This article tested pH values with 3rd grade water and KCl solution on variety of fabrics in order to choose the best extraction medium when test.The results showed that the veracity and stability of pH value were improved by addition of KCl solution,when pH value is close to neutral and alkaline. |
