Extraction of lanthanides and iron from acidic matrix solution produced from monazite processing using chemically modified resins

Abstract

Nowadays chelating polymeric materials represent efficient materials in environmental and industrial applications due to their efficiency, selectivity, durability, easy handling and availability from both synthetic and natural sources. The necessity to separation and extraction Rare earth metals (REMs) because They are becoming increasingly important because of their unique chemical and physical properties and their applications in the field of chemical engineering, metallurgy, nuclear energy, optical, magnetic, luminescence and laser materials, high temperature superconductors and secondary batteries, etc. Chitosan and Alginate are an important natural polymer because of its unique properties like biodegradability, biocompatibility. The major goal of the present thesis is the preparation and characterization of modified chitosan and Alginate resins. The adsorption behaviour of the resins obtained towards lanthanides and iron will also studied using batch methods. The study will proceed according to the following program:

1. Loading of chitosan with different chelating groups such as, amine, and amino acid group. 2. Synthesis Magnetic nano¬composite alginate beads 3. . Studying the uptake behavior of the obtained resins towards lanthanides and iron in aqueous solutions at different experimental conditions of pH, time, temperature and pollutant concentration. 4. Kinetic and thermodynamic characteristics of adsorption reaction will also investigate. 5. Studying the regeneration of the loaded resins. 6. Application the obtained resin on real sample.
