Preparation of Nanoparticles of Calcium Oxalate Dihydrate

Article Preview

Abstract:

Calcium oxalate dihydrate (COD) nanoparticles with an average size of about 200 nm was prepared by complex precipitation method using potassium oxalate (K2Oxa) and CaCl2 as raw materials, NTA as complexing agent. The effects of initial reactant concentrations, pH in reaction system and dispersion media on morphology and size of the nanoparticles were investigated. The samples were characterized by X-ray diffraction (XRD), Fourier transform infrared resonance (FTIR), zetasizer Nano-ZS and transmission electron microscopy (TEM). The results indicated that the prepared sample was COD and its morphology was nearly all elliptical.
