초록

연안 준설퇴석물을 열처리, 생물침출공정을 이용한 중금속처리, 중화처리 등의 다양한 방법으로 전처리한 재료를 이용하여 연안해수에 함유된 질산염의 흡착특성에 대한 실험실적 연구를 수행하였다. 전처리된 퇴적물의 흡착평형시간은 생물침출-열처리 퇴적물이 17분으로 가장 빨랐으며 생물침출-중화-열처리 퇴적물과 생물침출퇴적물이 각각 25분. 27분으로 황토와 열처리 황토에서의 3,3분, 32분 보다 빠르게 흡착되는 것으로 평가되었다. 시험된 재료들에 대한 흡착공정은 Freundlich 등온흡착식으로 해석할 수 있었으며, 전처리한 퇴적물의 흡착속도가 황토에 비해 빠름을 알 수 있었다. 질산염의 흡착량은 퇴적물과 열처리 퇴적물에서 각각 2.l2, 2.19 mg NO3-N/g 으로 가장 많았으며 열처리 등으로 전처리된 퇴적물은 연안해수의 수질개선을 위한 흡착재로서 활용 가능한 것으로 평가되었다.

A laboratory study on the adsorption of nitrate in polluted coastal water using various materials including several types of dredged sediments(ST) and yellow c1ays(YC), which are activated by heat(HT), bioleaching for heavy metal removal(BL) and neutralization(NR) was performed. The equilibrium time of the adsorption for the sediment bioleached and treated by heat(BL-HT-ST) was only 17min which was faster than the sediment bioleached, neutralized and treated by heat(BL-NR-HT-S) (25min) or the sediment treated by the bioleaching process(BL -ST)(27min), but longer equilibrium times for yellow c1ay(YC) or heat treated yellow day(HT- YC) were required. The adsorption processes of nitrate in sea water for tested material could be described by Freundlich isotherm, but were significantly affected by surface characteristics of the materials. The adsorption capacities for raw sediment and heat treated sediment were 2.12 and 2.19mg NO3-N/g, respectively, which were higher than others, indicating that the sediment activated by heat could be used as a material for the improvement of nearshore water quality.
