Embodiment 1
[0046] B: Heating the reaction kettle, and putting the vanadium pentoxide which is 9.84% of the total weight ratio of the vanadium liquid to be prepared and the sulfuric acid of 38.52% by weight into the hydrochloric acid by a stirring device The above-mentioned mixed solution is stirred at a speed of 60 to 80 rpm, and the reactor is continuously heated while stirring;
[0047] C: Gradually add oxalic acid whose weight accounts for 12.3% of the total weight ratio of the vanadium liquid to be prepared into the mixed solution in the step B, while maintaining the stirring device to stir the above mixed solution at a speed of 60 to 80 rpm , while stirring, continue to heat the reactor until the temperature of the mixed solution in the reactor is 80 degrees Celsius;
[0048] D: After adding the above-mentioned substances, when the constant temperature is 80 degrees Celsius, the mixed solution is continuously stirred at a speed of 60 to 80 rpm for 1.5 hours;
[0049] E: Stop stirri...
