Nontoxic copper-iron based silver stripping solution and stripping technology thereof

The invention provides a nontoxic copper-iron based silver stripping solution and a stripping technology thereof. The stripping solution comprises following components in percentage by weight: 8 to 12% of oxidizing agent, 25 to 45% of complexing agent, 3 to 9% of composite surfactant, and the balance being water, wherein the oxidizing agent is a composition of hydrogen peroxide and ammonia water,the complexing agent comprises glycine, citrate, and triethanolamine, and the composite surfactant comprises an alkyl glycosylamine type surfactant and an anion type surfactant. By improving the formula of the stripping solution, the osmotic effect of the stripping solution is effectively enhanced, the electrolysis efficiency is obviously improved; the stripping period is short, the content of free ions is less than 0.08%; the comprehensive stripping performance is strong, the product quality is guaranteed effectively after stripping; and moreover, the stripping solution does not contain any toxic pollutant, can be de
