摘要
根据GB/T 7573-2009《纺织品水萃取液pH值的测定》,研究了采用去离子水与氯化钾作为萃取介质所测得的纺织品pH值是否存在差异,以及该差异对最终判定结果的影响。结果表明弱酸性、强碱性样品经两种不同萃取介质处理后pH值相差不大,中性及弱碱性样品经两种不同萃取液处理后pH值差异较明显。
According to GB/T 7573--2009 "textiles-determination of pH of aqueous extract", the differences of measured textile pH value using deionized water and potassium chloride solution as the extraction medium were studied, and the influences of the differences on the final determination results for the laboratory were discussed. The results showed that the pH vale difference for weakly acidic and strongly alkaline samples treated in two extraction mediums was small, but great difference for the samples with neutral and weak alkaline.
