| 摘要:本研究针对成人纸尿裤在实际使用中面临的臭味物质复杂性，筛选并确定了9种代表性臭味化合物。通过综合运用检知管法、液相色谱-质谱和热脱附-气相色谱-质谱法的对比测试研究，建立了一套科学的成人纸尿裤消臭效果检测体系，对市售不同品牌成人纸尿裤的消臭效果进行了评价。结果表明，部分样品对异戊酸、2-壬烯醛和吲哚等化合物具有超过98%的消臭效果；添加了抑菌原材料的消臭型成人纸尿裤，对于氨气的消臭效果通常超过70%，显著优于普通型纸尿裤的消臭效果（不足30%）；而所有成人纸尿裤对甲硫醇等化合物的消臭效果均需改进。 |
| Abstract:This study screened and determined nine representative malodorous compounds in view of the complexity of malodorous substances faced by adult diapers in actual use. Through a comparative test study comprehensively using the detection tube method， liquid chromatography-mass spectrometry， and thermal desorption-gas chromatography-mass spectrometry， a scientific detection system for the deodorization effectiveness of adult diapers was established， and the deodorization effectiveness of different brands of adult diapers on the market were evaluated. The results showed that some samples had deodorization effectiveness of more than 98% on compounds such as isovaleric acid， 2-nonenal， and indole. The deodorant adult diapers added with antibacterial raw materials usually had deodorization effectiveness on ammonia of more than 70%， which was significantly better than the deodorization effectiveness of ordinary diapers （less than 30%）. However， the deodorization effectiveness on compounds such as methanethiol still needed to be improved. |
