초록

활성탄 담지 팔라듐 촉매상에서 하이드라진에 의한 용존산소의 환원반응을, 15- 35℃, 하이드라진/용존산소의 초기 농도비가 1.5-5, 촉매/물의 비율이 0.025-0.2g L^-1인 조건에서 조사하였다. 반응차수는 하이드라진에 대해 1/2차, 산소에 대해 1차로 근사할 수 있었으며, 활성화에너지는 52kJ mol^-1로 얻어졌다.

The reduction reaction of dissolved oxygen in water by hydrazine over acti- vated carbon-supported palladium catalyst was studied at 15-35℃. The initial concentration ratio of hydrazine to dissolved oxygen was varied within 1.5-5, and the ratio of catalyst mass to water volume within 0.025-0.2g L^-1. The reaction order for hydrazine could be approximated to 1/2 and for dissolved oxygen to 1, respectively. Activation energy was determined to be 52kJ mol^-1.

Keywords:Dissolved Oxygen;Pd/C;Hydrazine;Kinetics
