Embodiment 1
[0039] A water-based alkaline electrolyte, comprising the following raw materials in parts by weight: 150 kg of water, 100 kg of weakly alkaline salt, and 0.5 kg of a thickener;
[0040] The weakly basic salt is: potassium acetate;
[0041] The thickener is sodium polyacrylate.
[0042] The preparation method of described aqueous alkaline electrolyte, comprises the following steps:
[0043] (1) Dissolving the weakly basic salt in water, and stirring and mixing evenly to obtain a weakly basic salt solution;
[0044] (2) adjust the pH of the weakly alkaline saline solution to be 8.5-9.5;
[0045] (3) After stirring and mixing, add a thickener to the solution obtained in step (2), and stir and mix evenly to obtain the aqueous alkaline electrolyte.
Embodiment 2
[0047] A water-based alkaline electrolyte, comprising the following raw materials in parts by weight: 300 kg of deionized water, 200 kg of weakly alkaline salt, and 1 kg of thickener;
[0048] The weakly basic salt is: potassium acetate;
[0049] The thickener is: sodium polyacrylate.
[0050] The preparation method of described aqueous alkaline electrolyte, comprises the following steps:
[0051] Dissolve potassium acetate in water, and stir to mix evenly to obtain weakly alkaline saline solution;
[0052] Its chemical formula is: CH3COOK=CH3COO-+K+
[0053] The chemical equation for further hydrolysis of acetate ion is:
[0054] CH3COO-+H2O≒CH3COOH+OH-
[0055] Potassium acetate is dissolved in water and undergoes hydrolysis to produce hydroxide ions, which provide hydroxide ions for the electrochemical oxygen sensor;
[0056] (2) Use the potassium hydroxide of 0.1mol / l to adjust the pH of weakly alkaline saline solution to be 8.5; ensure that the pH of the electrolyte ...
Embodiment 3
[0060] A water-based alkaline electrolyte, comprising the following raw materials in parts by weight: 200 kg of deionized water, 150 kg of weakly alkaline salt, and 0.8 kg of a thickener;
[0061] The weakly basic salt is: sodium acetate;
[0062] The thickener is: sodium carboxymethylcellulose.
[0063] The preparation method of described aqueous alkaline electrolyte, comprises the following steps:
[0064] (1) Sodium acetate is dissolved in water, and stirred and mixed evenly to obtain weakly alkaline saline solution;
[0065] Its chemical formula is: CH3COONa=CH3COO-+Na+
[0066] The chemical equation for further hydrolysis of acetate ion is:
[0067] CH3COO-+H2O≒CH3COOH+OH-
[0068] Sodium acetate is dissolved in water and undergoes hydrolysis to generate hydroxide ions, which provide hydroxide ions for the electrochemical oxygen sensor.
[0069] (2) Use the potassium hydroxide of 0.1mol / l to adjust the pH of the weakly alkaline saline solution to be 9; ensure that th...
