STUDY ON ADSORPTION CAPACITY OF LEAD (II) IN SOLUTION BY COMPOSITE MATERIAL Fe3O4 -TEA RESIDUE
Abstract
This paper presents the results obtained for studying the adsorption capacity of Pb2+ in the solution of adsorbed materials made from Fe3O4 and tea residue. In solution of Pb2+ with initial concentration of 5÷10 mol /l, the efficiency of adsorption of Pb2+ on Fe3O4 - tea residue obtained is very high (over 90%). The adsorption of Pb2+ ions occurs on well-fabricated materials and follows both Langmuir and Freundlich equations. Adsorption of Pb2+ ions occurs on material Fe3O4 - tea residue is favorable and follows both Langmuir and Freundlich equations.
