[0002] Water is the source of life. With the continuous pollution and shortage of water resources on the earth, disinfection water treatment is becoming more and more important. At present, in terms of the types of water disinfection, there are chlorine, sodium hypochlorite, chloramine, Ultraviolet lamp disinfection mode; in the above disinfection modes, due to the increase of various organic substances in groundwater quality in recent years, the use of chlorine disinfection will produce mutagenic and carcinogenic organic compounds such as trihalomethanes; chloramine disinfection requires a longer period of time. The contact time and operation are more complicated, and the bactericidal effect of chloramine is poor; while the ultraviolet sterilizing effect is only effective during its irradiation period, once the treated

Example Embodiment

[0050] Example 1-5

[0051] In Examples 1-5, the ions of each component and the molar percentage of ions are shown in the following table:

[0052] Table 1 Example 1-5 components and ratio

[0053] Nd 3+

[0054] -Means that the component is not contained

[0055] Among them, the neodymium ions of Example 1 are from neodymium chloride and neodymium nitrate, the europium ions are from europium chloride and europium nitrate, and the ytterbium ions are from ytterbium sulfate and ytterbium carbonate; the ytterbium ions of Example 2 are from ytterbium nitrate, and the gadolinium ions are from chloride. Gadolinium, gadolinium nitrate, gadolinium sulfate, dysprosium ions are derived from dysprosium nitrate and dysprosium sulfate; the europium ions in Example 3 are derived from europium nitrate, the gadolinium ions are derived from gadolinium sulfate and gadolinium carbonate, and the dysprosium ions are derived from dysprosium chloride, dysprosium nitrate, and dysprosium sulfate; implement...

Example Embodiment

[0057] Experimental example

[0058] The chlorine evolution accelerator of Examples 1-5 was introduced into the sodium hypochlorite generator electrode to test the effect of the chlorine evolution reaction and the chlorine evolution efficiency of the sodium hypochlorite generator electrode.

[0059] The experimental steps are as follows:

[0060] (1) Use a titanium plate with a titanium content of 99.9% and a thickness of 1mm as the substrate. After the titanium plate is sandblasted and polished to remove the oxide layer, it is placed in a 10% NaOH solution to shake for 30 minutes, and then 20% oxalic acid is used The solution is used to etch the titanium plate for 2 hours, and then place it in ethanol solution for later use after cleaning;

[0061] (2) Preparation of active coating solution: use the mixed solution of n-butanol: isopropanol=2:1 as the solvent, and use ruthenium trichloride, chloroiridic acid, tetrabutyl titanate, and chlorine evolution accelerator as the solute. Conc...

Abstract

The invention discloses a chlorine evolution accelerator and a preparation method thereof. The chlorine evolution accelerator is prepared from three or more of a neodymium compound, a europium compound, an ytterbium compound, a gadolinium compound and a dysprosium compound. The chlorine evolution accelerator is added to an electrode of a sodium hypochlorite generator so that the electrode of the sodium hypochlorite generator is high in chlorine evolution speed, high in electrolysis efficiency and low in operation cost. The invention aims at providing the preparation method of the chlorine evolution accelerator, the reparation method is simple in process, easy to operate, and conductive to large-scale and industrialized production.
