Abstract
The work presented in this thesis reports the synthesis and application of some novel Ag+-selective ligands and magnetic iron oxide /Ag+-ligand nanocomposites for Ag+ recovery from aqueous solutions. Also investigated is the Ag+-selective ligand binding studies using traditional methods including mass spectrometry and proton NMR titrations. Chapter 1 provides a detailed introduction to methods of metal recovery leading to discussion of adsorption technology and ending with a detail review of types of iron oxide/ligand composites for metal recovery.
Chapter 2 reports on a novel room temperature route to accessing a range of novel N,N’-malonamide derivatives and styrylamide Ag+-selective ligands, and the measurement of their efficiency and selectivity for Ag+ extraction from aqueous solution.
Chapter 3 presents a detailed investigation of the binding stoichiometries of two Ag+ selective ligands (N,N’-malonamide derivatives and styrylamide) with Ag+, using mass spectrometry and proton NMR titrations (leading to Job’s and mole ratio plots).
Chapter 4 focuses on the synthesis of iron oxide nanoparticle and its linkage to a novel styrylamide Ag+-selective ligand by means of atom transfer radical polymerization (ATRP) and free radical polymerization (FRP) and ending with testing of the iron oxide/styryl amide nanocomposite obtained for Ag+ recovery from aqueous solution.
Chapter 5 describes the synthesis of iron oxide/imidazolium-based Ag+-ligand nanocomposite and the optimization of parameters (pH, time, dosage and stripping agent) for efficient and selective Ag+ recovery from aqueous solutions.
Chapter 6 details the experimental procedures and chemical analyses undertaken in this thesis.
