概要
- 論文の詳細を見る
Tyramine was polymerized by an enzymatic reaction with horseradish peroxidase, and the polymer was used in the recovery of precious metals from acidic media. The obtained poly(tyramine) was a macroporous aggregate of particles and had a molecular mass of 1700 Da. In HCl solution, platinum and palladium were selectively adsorbed to the amino group in poly(tyramine). Poly(tyramine) had an adsorption capacity of 0.65 mol/kg for platinum and 0.51 mol/kg for palladium in 5.0 mol/L HCl. These results demonstrate the polymer could be applied to treatment of wastewater containing precious metals.
