Stabilized electromagnetic base liquid, formation thereof and application to high-salt wastewater treatment

A method for preparing a stabilized electromagnetic base liquid comprising the following steps:

• Step 1:
• as weight ratio, weigh and take 20-30 parts of alkali metal hydroxide and 20-30 parts of non-alkali metal;
• mix the alkali metal hydroxide and non-alkali metal uniformly to obtain the mixture;
• Step 2:
• add a first part of ammonia water to the mixture for a reaction of 1-2 hours, obtaining the preliminary reaction mixture;
• as weight ratio, the first part of ammonia water is 1 to 2 parts of ammonia and 20 to 40 parts of water;
• Step 3:
• when the temperature of preliminary reaction mixture reaches 110°, add a second part of ammonia water to the mixture for a reaction of 4-6 hours;
• control the reaction temperature between 110-160°, obtaining the complete reaction mixture;
• as weight ratio, the second part of ammonia water is 1 to 4 parts of ammonia and 10 to 40 parts of water;
• Step 4:
• as weight ratio, add 1-60 parts of water to the complete reaction mixture for dilution, obtaining the diluted mixture;
• Step 5:
• filter the diluted mixture and let it stand for 10-24 hours, obtaining the filtrate;
• Step 6:
• apply a plasma generator with direct current to process the filtrate by the plasma jet generated in the discharge process to obtain a electromagnetic base liquid with following characters:
• a pH value between 12 and 14;
• oxidation reduction potential value between −1.0 and −1.8 v;
• with no corrosivity;
• and with stabilized hydrated electrons (eaq−−).
