| titleOfInvention | Tin stripping solution, method for removing tin-containing layer on substrate and method for recycling tin |
| abstract | The invention discloses a tin stripping solution, a method for removing a tin-containing layer on a substrate and a method for recovering tin. Described tin stripping liquid comprises the electrolyte of 20g/L-480g/L, the antioxidant of 1g/L-40g/L, the stabilizer of 0.5g/L-20g/L and nitric acid, wherein, described electrolyte comprises sulfuric acid, amino acid At least one of sulfonic acid and methanesulfonic acid, wherein the content of nitric acid is 0.1%-5% of the total volume of the tin stripping solution. The tin stripping solution according to the present invention contains a very small amount of nitric acid, so a large amount of heat is not generated, and there is basically no gas emission, thus reducing the pollution to the environment. |
