چکیده
In the present study, the optimization of immobilization structures along with Scenedesmus sp. and the determination of heavy metals (Ni, Cr) absorption rate have been investigated. Polymers in combination with salts were performed in alginate in order to study the stability of formed structures in cross linking agents. Beads with stable structure in synthesized heavy metal solution inoculated and the adsorption percentage has been recorded. Results showed that the most stable beads were formed in 2 and 3% alginate along with CaCO3 application beside BaCl2 as solidified solution. Reduction of heavy metal in these structures had the most percentage and it was observed that if the incubation time of beads in solidified solution decreased, the percentage of heavy metal reduction would increase to 86%. Although alginate beads showed the highest absorption rate of heavy metal, the presence of S. sp. in all treatments occasionally increased heavy metal absorption up to 15%.
