摘要
在光化学反应器中对三乙烯四胺合钴(Ⅲ)离子的还原过程进行了研究,考察了反应温度、溶液初始p H值、反应时间以及加入不同的Cu^(2+)量和I-量对还原过程的影响。实验结果表明:光化学对三乙烯四胺合钴(Ⅲ)离子的还原反应具有一定的影响;反应的最佳温度为70℃;最佳p H值为2.05;最适宜的反应时间为40 min;加入Cu^(2+),I-对三乙烯四胺合钴(Ⅲ)还原反应均有促进作用,其转化率分别随着加入Cu^(2+),I-浓度的增加而升高。
The reduction process of [ Co (trien) (H2O)2]^3+ in the photochemical reactor was studied. The influences of reaction temperature, the initial pH value of reaction solution, reaction time and the different amount of adding Cu2+ and I- on the reduction were investigated. The results show that the photochemistry has a certain effect on the reduction reaction of [ Co (trien) (H2O)2]^3+ The optimal temperature is 70 ℃. The best pH is 2.05. The most suitable reaction time is 40 min. Adding Cu2+ and I- has a promoting effect on the [Co (trien)(HzO)2]^3+ reduction reaction and the conversion increases with the increasing concentration of the adding Cu2+ and I-. Key words:
