[0036] A preparation method for electroplating sewage treatment agent, comprising the following steps:
[0037] A. Add the propylene glycol into the organic solvent and stir for 15-30min at 10-30°C to obtain a clear solution A;
[0038] B. Under the condition of continuous stirring, add divalent manganese ions to solution A, and continue stirring for 20-30min to obtain yellow solution B;
[0039] C. Under the condition of continuous stirring, add the benzenesulfonamide to the solution B, and keep stirring for 15-20min to obtain a yellow solution C;
[0040] D. Under the condition of continuous stirring, add the sodium azide to the solution C, the solution becomes turbid, continue to stir until the solution is clear again, and obtain the yellow solution D;
[0041] E. Under the condition of continuous stirring, add sodium carbonate to the solution D to adjust the Ph value to 11-13 to obtain the electroplating sewage treatment agent.
[0042]As a preferred solution, diethyl et...
