Abstract: This work concerns with the preparation, characterization and application of vegetable stalks alginate biosorbent beads (Bagasse-calcium alginate and Jatropha curcas calcium alginate) which were prepared by the association of bagasse waste powder or Jatropha curcas powder and calcium alginate via sodium alginate. Calcium alginate beads are formed when sodium alginate salt is added dropwise to a fixing solution of calcium chloride.
