【摘要】 介绍了抗坏血酸应用于水处理行业的优点,研究了硫酸铜对抗坏血酸除氧效率的影响,考察了水的pH值、温度及抗坏血酸浓度对有无添加剂时抗坏血酸的除氧效率的影响,试验结果表明:水的pH值及温度对抗坏血酸的除氧效率均有影响;当添加CuSO₄·5H₂O后,抗坏血酸的除氧效果有了很大的提高,CuSO₄·5H₂O的加入使抗坏血酸达到同样除氧效果时的添加量减小至少80%,有利于减少生产成本及抗坏血酸在实际工业用水除氧领域的应用。更多还原

【Abstract】 The advantages of ascorbic acid applied in water treatment industry are introduced,and the effect of copper sulfate on the deoxygenation efficiency of ascorbic acid is also studied.The effects of pH value,temperature of water and ascorbic acid concentration on the deoxygenation efficiency of ascorbic acid with or without additives are investigated.The results show that the pH value and temperature of water have influence on the deoxygenation efficiency of ascorbic acid.When CuSO₄·5 H₂O is added, the deoxygenation of ascorbic acid is greatly improved, and the addition of CuSO₄·5 H₂O can reduce the addition amount of ascorbic acid by at least 80% when it reaches the same deoxygenation effect, which is beneficial to reduce the production cost and the application of ascorbic acid in the field of industrial water deoxygenation.更多还原
