| description | The invention discloses a method for preparing an ultra-roughening solution from a regenerated solution obtained after copper recovery and an ultra-roughening method.The method for preparing the ultra-roughening solution comprises the following steps that ethyl alcohol and deionized water are added into a silane coupling agent for hydrolysis, silane hydrolysate is prepared, and the volume percentage of the silane coupling agent to the ethyl alcohol to the deionized water is 5: 35: 60; adding the prepared silane hydrolysate into the regenerated liquid, wherein the addition amount of the silane hydrolysate is 2-3% of the volume of the regenerated liquid; formic acid is added into the regeneration liquid, the super-roughening liquid is prepared after uniform stirring, and the addition amount of the formic acid is 3-5% of the volume of the regeneration liquid. According to the super-roughening liquid prepared by the method, a micro adsorption layer is formed on a copper surface by using the coupling agent, and a |
