Method for preparing cesium- absorbent having Prussian blue on the surface by reforming the surface of polymer containing hydroxyl group using acrylic acid

The present invention relates to a method of forming stable Prussian blue by converting a hydrophilic functional group -OH in porous pores made of PVA sponge and cellulose nonwoven fabric to a carboxyl group using acrylic acid, thereby generating negative charges on the surface of the PVA sponge and...

Beschreibung
Zusammenfassung:	The present invention relates to a method of forming stable Prussian blue by converting a hydrophilic functional group -OH in porous pores made of PVA sponge and cellulose nonwoven fabric to a carboxyl group using acrylic acid, thereby generating negative charges on the surface of the PVA sponge and cellulose, and increasing the binding force with Prussian blue. 본 발명은 PVA 스펀지 및 셀룰로오스 부직포 소재의 다공성 기공 안의 친수성 기능기 그룹인 -OH를 아크릴산을 이용하여 카르복실기로 바꿔주어 PVA 스펀지 및 셀룰로오스 표면에 음전하가 생성되고, 이로 인하여 프러시안 블루와의 결합력이 증대되고 안정적인 프러시안 블루가 형성되는 방법에 관한 것이다.
