Abstract

Extraction of minerals in deionized water and elimination effect of heavy metals in water by Nohwado Quartz Porphyry were examined. When the Nohwado Quartz Porphyry was immersed and stirred in deionized water at 0.5, 1.0, 1.5 and 2.0% concentration for 3 hours, various minerals concentration of the all stirred water were suitable for potable water. Particularly, when the lead, copper, cadmium and arsenic solution were shaked with Quartz Porphyry at $20^{\circ}C$ for 24 hours, the elimination rate of each mineral was 99.5, 99.9, 95.0 and 66.5%, respectively.

노화도산 맥반석으로부터 미네랄 용출은 맥반석 농도 0.5, 1.0, 1.5, 2.0%를 탈이온수에 첨가하여 3시간 교반했을 때 전 농도에서 음용수 수질기준에 적합한 양질의 식수를 얻을 수 있었다. 노화도산 맥반석의 흡착 및 여과기능은 단일 용액으로 존재하는 중금속에서 제거효율이 가장 좋았으며 그 중에서 특히 납, 구리, 카드뮴, 그리고 비소 등을 실온에서 24시간 진탕했을 때 제거율은 각각 99.9, 99.9, 95.1, 66.5% 였다.
