[0041] Water: 60 parts;

[0042] Specifically, the cross-linked starch, carbon disulfide and sodium hydroxide are all in powder form, and the particle size is 0.2-0.8um.

[0043] Specifically, the cross-linked starch is epichlorohydrin cross-linked starch.

[0044] Instructions:

[0045] Specifically, the following steps are included:

[0046] a) Mix cross-linked starch and dicumyl hydroperoxide and place them in a kneader, kneading for 1 hour at a temperature below 40°C;

[0047] b) Mix the material obtained in step a wit...

[0066] Instructions:

[0067] a) Mix cross-linked starch and dicumyl hydroperoxide and place them in a kneader, kneading for 1 hour at a temperature below 40°C;

[0068] b) Mix the material obtained in step a with carbon disulfide, sodium hydroxide, and water and place it in a reactor, heat the reactor to 60-70°C and vacuumize and keep it warm for 2 hours, and adjust the pH to 7.0-8.0 to obtain Group A Minute;

[0069] c) Add component A to the circuit board waste water until the pH is 9.0-10.5, fu...

[0074] Including the following weight percentages of A component and B component:

[0075] Among them, component A contains cross-linked starch: 20 parts;

[0076] Dicumyl hydroperoxide: 10 parts;

[0077] Carbon disulfide: 15 parts;

[0078] Sodium hydroxide: 25 parts;

[0079] Water: 80 parts;

[0080] Wherein, component B contains polyferric sulfate: 15 parts;

[0081] Polyaluminum ferric chloride: 15 parts;

[0082] Polyacrylamide: 12 parts;

[0083] Water: 60 parts;

[0084] Using method is with embodiment 2,

[0085] Table 3 is a comparison table of copper content and CODcr index when the final pH of the high-efficiency copper removal agent is 8 after being added to the wastewater.

[0086]

[0087]

[0088] Comparing with Example 2, it can be known that the total copper removal rate and CODcr removal rate change are small.
