초록

활성탄에 의한 암모니아 구리착물의 흡착 특성에 대하여 연구하였다. 활성탄 비표면적을 BET 흡착장치에서 측정하였고, 암모니아수용액에서 암모니아 착물을 이용하여 Cu(Ⅱ)이온 제거 특성과 활성탄에 의한 착물흡착에서 암모니아착물 형태에 대하여 연구하였다. 실험 결과 비표면적 크기는 mesh No.가 감소할 수록 증가하였고, 활성탄에 의한 Cu(Ⅱ)이온 흡착은 pH 6 범위가 적합함을 알았다. 또한 암모니아수용액에서 암모니아 구리착물이 활성탄에 흡착되는 형태는 [Cu(NH₃)₂]²⁺와 [Cu(NH₃)₃]²⁺로 흡착됨을 알았으며, 암모니아 농도는 2.25×10^-3∼2.25×10^-3(mol/ℓ) 범위에서 검토하였다.

The adsorption characteristics of ammonia-Cu(Ⅱ) complex on activated carbon were studied. Firstly, the specific surface area of the activated carbon was measured by using the BET adsorption apparatus. Secondly, the characteristics of the removal copper(Ⅱ) ion from aqueous ammonia solution by forming a complex with ammonia and then by the adsorption of the complex on the activated carbon were studied. It was found that the specific surface area increases with decreasing the mesh number of the activated carbon, and the optimum pH for the adsorption of the Cu(Ⅱ) ion on she activated carbon was found to be approximately 6. It was also found that the adsorbed Cu(Ⅱ)-ammonia complexes on the activated carbon in the aqueous ammonia solution have two types, depending on the concentration of the solution ; i.e. [Cu(NH₃)₂]²⁺ and [Cu(NH₃)₃]²⁺ for 2.25×10^-4(mol/ℓ) and 2.25×10^-3(mol/ℓ), respectively.
