Abstract

인구증가와 개발 도상 국가의 산업 활동 증가로 인해 대기 중 미세먼지농도가 상승함에 따라 생태계에 미치는 영향이 심각해지고 있다. 그로인해 미세먼지발생을 줄이기 위한 정책을 수립하여 시행하거나 미세먼지를 여과해주는 공기 청정기나 마스크의 연구가 활발히 이루어지고 있다. 본 연구에서는 전기방사실험을 통해 셀룰로스 아세테이트 파이버 필터를 제조하고 고분자용액에 활성탄을 첨가하여 미세입자 제거에 미치는 활성탄의 영향을 평가하였다. 미세입자 생성을 위해 염화나트륨 수용액을 사용하였으며, 공기 중 수분의 영향을 배제하기 위해 건조기를 설치하여 수분을 제거 한 후 필터 성능을 분석하였다. 활성탄이 첨가될수록 미세입자 제거 효율은 증가하였으며, 아세톤 흡착량 또한 증가하 였다.

The negative effects on ecosystem are getting serious due to the increase of particulate matters (PM) in the air by the increase of the number of population and the industrial activities. Thus, there have been a lot of environmental policies and researches of air purification system and filter mask to relieve the environmental problem. In this research, activated carbon impregnated cellulose acetate fiber filters produced using an electrospinning technique are studied for air purification. NaCl aqueous solution was used to generate PM and the humid air with NaCl PM was dried using a dehumidifier for the filter performance test. Filtration efficiency was increased with the increase of activated carbons , and acetone adsorption capacity was enhanced.
