Hybrid Type, Electrolytic Method consists of the electroflotation using soluble aluminum electrodes and the electrolytic dissolution using insoluble electrodes. The purpose of this theme is to suggest the optimization of the design and the operating parameter using cyano-complex as a toxic substanceFrom the batch electroflotation experiment, the separation rate is a function of the electricity per unit volume of liquid and presented by the first order kinetics. The rate constant increases with the decrease of the current density and with the decrease of pH and reaches about pH8-9 at the final separation period. The effect of the structure of electrodes on the separation efficiency is examined by the continuous experiments. As the result, the separation efficiency is improved by using the bipolar electrode as compared with the monopolar oneThe metal electrodes, IrO_2, Pt and PbO_2 as the coated material are used in the dissolution experiments. Cyano-complex is decomposed using NaCl as an electrolyte, It suggests that the decomposition is due to the chloride radical. The decomposition rate is a function of the electricity per unit volume of liquid. Ferricyanide changes to ferrocyanide by the electric oxidation. the ferrocyanide is decomposed rapidly by the chloride radical. In the latter process, iron ion formed by the oxidation is followed by the precipitate of ferric hydroxide. The decomposition rate is improved in the order of PbO_2, Pi and IrO_2From hybrid type, electrolytic experiments, the separation efficiency was almost 100% using IrO_2 electrode which is higher durability and cheaper material than other metal electrodes

杂交类型，电解方法由使用可溶性铝电极和使用不溶性电极的电解溶解组成。该主题的目的是建议使用氰基复合物作为批处理电盘实验的有毒物质的设计和操作参数的优化，分离速率是每单位液体电量的电力的函数，并由一阶动力学提供。速率常数随电流密度的降低和pH值的降低而增加，在最后的分离期间达到了pH8-9。通过连续实验检查了电极结构对分离效率的影响。结果，与单极的金属电极，IRO_2，PT和PBO_2相比，使用双极电极通过在溶解实验中使用涂层材料来提高分离效率。蓝色复合物是使用NaCl作为电解质分解的，这表明分解是由于氯化物自由基引起的。分解速率是单位液体液体电量的函数。铁酰胺通过电氧化变为亚铁氰化物。氯氰化物被氯化物自由基迅速分解。在后一个过程中，由氧化形成的铁离子之后是铁氧化铁的沉淀。分解速率在PBO_2，PI和IRO_2的顺序上提高了杂种类型，电解性实验，使用IRO_2电极比其他金属电极更高的耐用性和更便宜的材料，分离效率几乎为100％
