정수기 성능평가장치를 이용한 가정용 정수기의 VOCs 용출특성 및 중금속 제거특성 연구

Abstract

This study developed a system for evaluating the performance of home water purifiers, and determined the leaching characteristic of 43 kinds of VOCs, which may leach out of water-purifier surface in contact with water, and measured heavy-metal removal rates, the basic indicator of the performance of water purifiers. In order to apply the water-purifier evaluation system, this study purchased three kinds of commercial reverse osmosis water purifiers for home use and another three kinds of ultrafiltration membrane water purifiers, and analyzed VOCs in extractives from the water purifiers and measured heavy-metal removal rates for Cu and Mn. According to the result, VOCs were not detected in extractives, and Cu and Mn were removed by over 90% in the reverse osmosis water purifiers, and Cu was removed by over 80% and Mn over 20% in the ultrafiltration membrane water purifiers.
