摘要:A synthesis method for carbazole phosphazene based polymer and a method for the recovery of precious metal elements from electronic waste materials are provided. The developed method allows for the efficient and cost-effective synthesis of carbazole phosphazene based polymer in a single step, with high yield and easy purification. In the method for the recovery of precious metal elements from electronic waste materials, a two-step metal leaching process is employed using solutions with different acidity levels, resulting in the high-efficiency recovery of precious metal elements. The carbazole phosphazene based polymer represented by Formula 2 exhibits high selectivity in the adsorption of precious metal elements, particularly gold. Therefore, it can be applied in the recovery of gold and other precious metals from electronic waste materials in the method for the recovery of precious metal elements.
