摘要

In this paper, the immobilized pellets were prepared by embedding Pichia pastoris (P. pastoris) with sodium alginate and used for the recovery of palladium ions in solution. The catalytic activity of immobilized Pd/P. pastoris for 4-nitrophenol (4-NP) was studied. The results showed that the recovery rate of Pd ions could be significantly increased by immobilized cells. The immobilized Pd/P. pastoris pellets showed good catalytic activity for the reduction of 4-NP, and the catalyst remained good catalytic activity even after multiple reuses.
