Embodiment 1
[0025] Ionic palladium activation solution for horizontal copper precipitation, each liter of ionic palladium activation solution includes the following components: palladium sulfate 10mg, 4-dimethylaminopyridine 0.5g, alkylphenol polyoxyethylene ether 15mg, ammonia water 22mL, cinnamaldehyde 8mg, polyamide-amine resin-glycine complex 2.5mg, the rest is deionized water.
[0026] Wherein, the polyamide-amine resin-glycine compound is made by the following steps:
[0027] The polyamide-amine resin whose algebra is G3.0 is added into water and stirred evenly to obtain a polyamide-amine resin solution with a mass concentration of 20%, and ethyl glycine is added to water and stirred uniformly to obtain a solution of ethyl glycine with a mass concentration of 4%. Mix polyamide-amine resin solution, ethyl glycine solution, and glutaraldehyde with a mass ratio of 1:0.2:0.1, raise the temperature to 50°C and stir for 24 hours to obtain a reaction solution, and use a dialysis bag with a...
