초록

본 연구에서는 역삼투 공정 농축수에 존재할 수 있는 내분비계 장애물질의 처리에 있어, 고급산화 공정의 적용가능성을 다양한 조건하에서 평가하였다. 오염물 제거에는 Fe(II)를 촉매로 한 과황산나트륨 산화를 이용하였으며, 초기 pH와 이온강도 등, 영향인자에 따른 산화능을 검토하였다. Fe(II) 촉매 과황산나트륨에 의한 $17{\alpha}$-ethynylestradiol(EE2) 제거효율은 초기 pH와 이온강도가 증가할수록 감소하였다. 반면, 이온강도 물질로 염소이온과 같은 할로겐족 이온을 적용 시 산화반응에 긍정적인 영향을 나타냈는데, 이는 라디칼 전이에 따른 영향으로 판단된다.

The objective of this study was to evaluate the oxidation method to remove endocrine disrupting chemicals in reverse osmosis(RO) retentate for the reuse of wastewater effluent. Oxidation of organic pollutants was induced by the persulfate catalyzed by Fe(II). Affecting factors such as initial pH and ionic strength on the Fe(II) catalyzed persulfate oxidation were evaluated. $17{\alpha}$-ethynylestradiol (EE2) degradation efficiency decreased as pH and ionic strength increased. However, the efficiency increased as chloride ion concentration increased due to the influence of radical transfer.
