摘要
分别采用全自动仪器法与GB 18401-2010《国家纺织产品基本安全技术规范》中的人工法对纺织品中的甲醛含量进行测定,对比了两种方法的标准工作曲线线性范围、方法准确度、方法精密度、空白加标回收率及实际样品的测定结果.结果表明,全自动仪器分析法线性范围良好,精密度和回收率可满足国家标准的相关要求,测定结果准确,与国标人工法相比不存在显著性差异.
Abstract
The content of formaldehyde in textiles is determined according to the automatic instrument method and national standard method by manual,and the standard working curve linear range,method accuracy,method precision,blank recovery rate and the measurement results of actual samples of the two methods are compared.The results show that the linear range of the automatic instrumental analysis method is good,the precision and recovery rate meet the relevant requirements of national standard,the measurement results are accurate and there is no significant difference from national standard method.
