| Zusammenfassung: | The present invention relates to a virgin pulp material having a heavy metal adsorption layer containing spherical hydrogel beads including chitosan and gelatin, and a method for manufacturing the same, wherein the adsorption material for selectively removing heavy metals comprises a heavy metal adsorption layer containing spherical hydrogel beads, thereby having an excellent heavy metal adsorption capacity. In addition, the virgin adsorption material for selectively removing heavy metals according to the present invention is capable of easily forming a heavy metal adsorption layer by injecting the heavy metal adsorption composition prepared by dispersing hydrogel beads and first paper material solution onto the rotating wire mesh of the Fourdrinier paper machine.
본 발명은 키토산과 젤라틴을 포함하는 구형 하이드로겔 비드를 함유하는 중금속 흡착층을 가진 천연펄프 소재 및 이의 제조방법에 관한 것으로, 상기 선택적 중금속 흡착 소재는 구형 하이드로겔 비드를 함유하는 중금속 흡착층을 포함함으로써, 중금속 흡착능도 우수한 장점이 있다. 또한, 본 발명에 따른 선택적 중금속 흡착 천연 소재는 중금속 흡착용 조성물에 하이드로겔 비드를 분산시켜 제조한 중금속 흡착용 조성물과 제1지료액을 회전하는 장망초지기의 망체 상에 각각 투입됨으로써 용이하게 중금속 흡착층을 형성할 수 있다. |
