Embodiment 1
[0021] A kind of method that reduces carbonate group, sulfate group in high-concentration potassium hydroxide solution, comprises the following steps:
[0022] S1. The filter filters the collected high-concentration waste potassium hydroxide solution to remove mechanical impurities.
[0023] S2. Heating the high-concentration potassium hydroxide solution to be treated to 80-100°C;
[0024] S3. Add 80-100 g / L barium hydroxide powder into the high-concentration potassium hydroxide solution to be treated, and keep stirring for 3-6 hours;
[0025] S4 stands still for 16 to 24 hours, and cools down naturally;
[0026] S5 filters the lye after standing still.
[0027] Further, in S1, a variable-frequency electric field is formed in the high-concentration potassium hydroxide solution, and treated for 1 to 2 hours. Preferably, the working electrodes 8-12A are the electrodes of the variable frequency electric field.
[0028] Further, the frequency range of the variable frequency el...
Embodiment 2
[0031] A kind of method that reduces carbonate group, sulfate group in high-concentration potassium hydroxide solution, comprises the following steps:
[0032] S1. The filter filters the collected high-concentration waste potassium hydroxide solution to remove mechanical impurities;
[0033] S2. Heat the high-concentration potassium hydroxide solution to be treated to 80-100°C; form a variable-frequency electric field in the high-concentration potassium hydroxide solution, and treat it for 1-2 hours; the working electrode of the variable-frequency electric field is 8-12A, and the variable-frequency electric field The frequency range is 40~50kHz;
[0034] S3. Add 80-100 g / L barium hydroxide powder into the high-concentration potassium hydroxide solution to be treated, and keep stirring for 3-6 hours;
[0035] S4 stands still for 16 to 24 hours, and cools down naturally;
[0036] S5 filters the lye after standing still.
[0037] Under the action of the variable frequency elec...
