Immobilize Algae To Removal Copper And Lead From Aquatic Ecosystem

Abstract

Laboratory experiments were performed to study Cu+2 and Pb+2
uptake by the unicellular green microalga Chlorella vulgaris
immobilized in calcium alginate beads. was carried out by using sodium alginate and calcium chloride bound with calcium alginate
to form the beads of the organism. In all immobilization samples, regular solutions of lead Immobilization and copper at
concentrations of (10, 20, 30, 40 and 50) ppm were used. The heavy metal concentrations were measured using the atomic
absorption device during the analysis. Also, Scanning electron microscope (SEM) was used to examine immobilization of algae on
calcium alginate. In order to remove trace elements from the aqueous solution, the immobilization of algae will typically lead to
an increase in biomass collection of trace elements and eventually increase the removal efficiency of Chlorella vulgaris.
