This study screened and determined nine representative malodorous compounds in view of the complexity of malodorous substanc-es faced by adult diapers in actual use. Through a comparative test study comprehensively using the detection tube method,liquid chroma-tography-mass spectrometry,and thermal desorption-gas chromatography-mass spectrometry,a scientific detection system for the deodoriza-tion 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 de-odorization effectiveness on compounds such as methanethiol still needed to be improved.
