H_2O_2-Fe^(2+)/TiO_2-H_2SO_4体系处理废有机溶剂的研究

Experimental Study on Treatment of Spent Organic Solvent(TBP/OK) by H_2O_2-Fe^(2+)/TiO_2-H_2SO_4

研究了废有机溶剂TBP/OK在H2O2-Fe2+/TiO2-H2SO4体系中的氧化分解行为,分析了H2O2用量、催化剂、温度、pH值对反应进程及结果的影响。在此基础上进行的“热”实验表明,废有机溶剂氧化分解所含放射性核素主要富集在反应残液中,基本没有二次转移或扩散。

A Study on the decomposition behaviours of spent organic solvert in H2O2-Fe2+/TiO2-H2SO4 system has been conducted, and the effects of many factors on the reaction process, such as H2O2 dosage, catalyst, temperature and pH value were analyzed. The ″hot″ test performed on the basis of the experiment demonstrated that after wet oxidation decomposition, the radioactive muclides loaded on SOS were predominantly enriched in the residues without diffusion to other phases. Therefore, the suitability and safety of the process were well verified.
