Study of Hydrazine Deoxygenation in Neutral Aqueous Solution

摘要: 介绍了中性水质中催化剂用量对催化联氨除氧效果的影响。试验条件为:温度10℃、20℃、30℃,初始溶解氧含量分别为10.0～10.8 mg/L(10℃)、8.2～8.6 mg/L(20℃)、7.0～7.4 mg/L(30℃),联氨用量为水中初始溶解氧含量的6倍、3倍。试验结果表明,催化剂用量为600～50μg/L时,水中溶解氧含量均可降至100μg/L以下。

Abstract: The efficiency of hydrazine deoxygenation added catalyst in the neutral aqueous solution is discussed.The test conditions are selected at temperatures of 10℃,20℃ and 30℃,the initial dissolved oxygen concentration of 10.0~10.8mg/L（10℃）,8.2~8.6mg/L（20℃） and 7.0~7.4mg/L（30℃）,and the hydrazine dosages are 6 and 3 times of the initial dissolved oxygen concentration.The results show that the dissolved oxygen concentration can be decreased to be 100μg/L when the catalyst dosage is within 600μg/L~50μg/L.
