Abstract
Chapter 1 contains literature survey about the different synthetic techniques of nano-polymeric materials of core shell structures. Also, it discusses the recent trends in removal of MB and lead from aqueous solution using nanocomposite adsorbents.
Chapter 2 discusses the instrumentation and theoretical consideration of advanced characterization techniques of nanomaterials such as TEM, DLS, AFM, SEM, EDX, XRF, Zetasizer, DSC, TGA and DTA.
Chapter 3 includes preparation and stabilization of magnetite nanoparticles to be used as a core. Also, it includes preparation of different types of magnetic silica nanospheres, core shell magnetic polymeric nanogels using different methods. Moreover, various types of organically modified montomorillonite core/polymeric shell nanoparticles were also prepared, and the control parameters of all preparation techniques were also discussed. The prepared nanomaterials were characterized using TEM, DLS, Zetasizer, XRD and FTIR.
Chapter 4 includes preparation of different series of crosslinkedpoly(sodium acrylate–co-acrylamide) nanocomposites of varied molar ratio of sodium acrylate: acrylamide; using different amounts of poly(sodium acrylate-co-acrylamide) core shell magnetic nanogels and montomorillonite/poly(styrene-co-acrylamide) nanopartiles. The prepared nanocomposites were characterized using AFM, SEM, Zeta potential measurements, XRD, FTIR, TGA, DTA and DSC.
Chapters 5-8 includes removal of methylene blue and Lead from aqueous solutions using poly(sodium acrylate-co-acrylamide) core shell magnetic nanogels and montomorillonite/poly (styrene-co-acrylamide) nanoparticles based on crosslinked poly(sodium acrylate–co-acrylamide) nanocomposites via batch adsorption techniques. The effects of initial dye concentration, contact time, solution pH, amount of loaded nanogels and temperature on MB adsorption were evaluated. The adsorption kinetics, isotherms and temperature-dependent performance, were investigated.
