Abstract: Abstract Copper (II) immobilized on l -arginine-β-cyclodextrin-functionalized magnetite nanoparticles (nano-Fe3O4@ l -arginine-CD-Cu(II)) were successfully synthesized and fully characterized using FT-IR, XRD, SEM, EDX, ICP, TGA and VSM techniques. The catalytic activity of these magnetically retrievable… read more here.
