摘　　要：本文依据GB/T 2912.1-2009《纺织品甲醛的测定第1部分:游离和水解的甲醛(水萃取法)》方法,采用AS5自动进样器和紫外可见分光光度计联用测定纺织品中的甲醛含量。与手动进样相比:自动进样测试的标准曲线的线性系数一致性好;分析过程中自动进样和清洗,无需人员干预,测试流程简单、效率高、结果准确,并可减少有毒有害样品对测试人员的人身伤害。自动进样测试一个样品仅需35s,实际样品消耗量4.8mL,对国标规定定容10mL的样品量满足自动进样器的需求。This paper is based on GB/T 2912.1-2009"Textiles-Determination of Formaldehyde-Part 1:Free and Hydrolyzed Formaldehyde(Water Extraction Method)",using AS5 automatic sampler and UV-visible spectrophotometer to determine formaldehyde content in textiles.Compared with manual injection:the linearity coefficient of the standard curve of automatic injection test is consistent;Automatic sample injection and cleaning during the analysis process,without human intervention,the test process is simple,efficient,accurate results,and can reduce the personal injury of toxic and harmful samples to the tester.The automatic sample injection test takes only 35s,and the actual sample consumption is 4.8mL.The sample volume of 10mL specified in the national standard can meet the requirements of the automatic sample injector.
