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 28. 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. |
