초록

본 연구에서는 석탄계 활성탄 신탄을 이용하여 입상활성탄 흡착공정에서의 nitrosamine류 9종의 흡착특성을 평가해 본 결과, nitrosamine류 9종의 물질별 파과 순서는 NDMA가 가장 빨리 파과에 도달하였고, 다음으로 NMOR, NPYR, NMEA, NDPA, NDEA, NPIP 순으로 나타났고, NDBA와 NDPHA의 경우는 운전 기간 동안 활성탄 처리수에서 검출되지 않았다. 석탄계 활성탄 신탄을 이용한 입상활성탄 흡착공정에서의 nitrosamine류 9종의 최대 흡착량(X/M)은 파과에 도달한 nitrosamine류 7종 중에서 NDMA가 $27.5{\mu}g/g$으로 가장 낮게 나타났으며, NPIP가 $671.0{\mu}g/g$으로 가장 높은 최대 흡착량을 나타내었고, NDBA와 NDPHA의 경우는 실험기간 동안 활성탄 흡착컬럼의 처리수에서 검출되지 않아 최대 흡착량을 구할 수가 없었다. 또한, 7종의 nitrosamine류에 대한 CUR의 경우는 NDMA가 1.07 g/day로 나타나 NPIP의 0.08 g/day 보다 13.4배 정도 높은 활성탄 사용률을 나타내었다. 석탄계 활성탄 신탄을 이용한 입상활성탄 흡착공정에서 파과에 도달한 7종의 nitrosamine류에 대해 최대 흡착량(X/M)과 $K_{ow}$값과의 상관성을 평가해 본 결과, 상관계수($r^2$)가 0.94로 나타나 양호한 상관성을 나타내었다.

This study accessed the adsorption characteristics of the nine nitrosamine species on coal-based granular activated carbon (GAC). The breakthrough appeared first for NDMA and sequentially for NMOR, NPYR, NMEA, NDPA, NDEA, and NPIP. On the other hand, NDBA and NDPHA were not detected in the treated effluent for the operation period. The maximum adsorption capacity (X/M) for the seven nitrosamine species with apparent breakthrough points ranged from $27.5{\mu}g/g$ (for NDMA) to $671.0{\mu}g/g$ (for NPIP). Carbon usage rate (CUR) for NDMA was 1.07 g/day, 13.4 times higher than that for NPIP (0.08 g/day). The X/M values for the seven nitrosamine species were fitted well with a linear regression ($r^2$ = 0.94) by their octanol-water partitioning coefficient ($K_{ow}$).
