Adsorption of Ni2+ on the surface of molecularly imprinted adsorbent from Penicillium chysogenum mycelium

Biotechnol Lett. 2003 Jun;25(12):949-53. doi: 10.1023/a:1024034232495.

Abstract

The adsorption capacity for Ni2+ on to the surface molecular imprinting adsorbent on Penicillium chysogenum mycelium (the surface-imprinted adsorbent) was 40-45 mg g(-1) (using 200 mg Ni2+ l(-1)), two times of the mycelium adsorbent. The surface-imprinted adsorbent had good stability at pH 2 to approximately 8. The optimal concentration of EDTA for desorption was 0.1 to 0.5 g l(-1). The surface imprinted adsorbent could be reused 15 times without losing its uptake.
