５％ヒドロキシアミン水溶液を含浸し、水洗することが
得られる。すなわち、繊維状の親水性空隙性材料にヒド
ロキシアミンがイオン交換的に付加されたアルデヒド捕
集材が得られる。It can be obtained by impregnating strongly acidic cationic fibers obtained using polypropylene fibers with a 5% aqueous hydroxyamine solution and washing with water. That is, an aldehyde-trapping material is obtained in which hydroxyamine is added to a fibrous hydrophilic porous material in an ion-exchange manner.
本例は、上記のように事務所の空気清浄器で、付加剤は
ヒドロキシアミンである。すなわち、アルデヒド濃度は
最高０、Ｏ８ｐｐｍ程度であるが、喫煙によりアルデヒ
ドが連続的に発生しているので、低濃度アルデヒドを迅

ヒドとの反応に富むヒドロキシアミンをイオン交換繊維
に付加（イオン交換的な付加）し、用いている。This example is an office air purifier as described above, and the additive is hydroxyamine. In other words, the maximum aldehyde concentration is about 0.8 ppm, but since aldehyde is continuously generated by smoking, it is necessary to quickly collect and remove low concentration aldehyde, so it is necessary to quickly collect and remove the low concentration aldehyde. Hydroxyamine rich in ion-exchange fibers is added to ion-exchange fibers (ion-exchange addition) and used.
イオン交換繊維の使用により、喫煙により生じたアルデ
ヒドに加え、アンモニア等イオン交換繊維自体で捕集さ
れる主にアルカリ性ガス等も同時に捕集、除去している
。By using ion-exchange fibers, in addition to aldehydes generated by smoking, ammonia and other alkaline gases that are collected by the ion-exchange fibers themselves are also collected and removed at the same time.
