Study of Immobilization and Removal Efficiency of Zn²+ from Wastewater by Anabaena Sp.

Methods and materials of immobilization of Anabaena sp. used in wastewater treatment were studied in this work .The results showed the polyurethane foam (PUF) could be an excellent organic polymer immobilization matrix, which can hold as much as 15 mg dry weight of Anabaena sp. by 1 cm
³
PUF. 70.2% efficiency of Zn
²⁺
cleansing in flowing wastewater at the speed of 3 mL/min could be reached.
