Abstract

In this study, zirconium based magnetic particles have been fabricated by co-precipitation method. Relationship between controllable input parameters (pre-stirring duration, stirring temperature, and post-stirring duration) and obtained response surfaces (zero point charge, pHZPC) for the fabrication of the magnetic particles is modelled through response surface methodology by using Box-Behnken design. The proposed model is: y=7.35295-0.00130x-0.02992x-0.01023x-0.00006x+ 0.00020X+0.00022x=0.00002x+0.00025-0.00009x where y is the pHZPC,x is the pre-stirring duration,x is the stirring temperature and x is the post-stirring duration. The magnetic particles are analysed by potentiometric titration, Fourier Transform Infrared spectroscopy (FTIR) and observed under microscope. Potentiometric titration determines the point of zero charge (pHZPC) of the magnetic particles. FTIR reveals the chemical bonding of the particles while microscope observation shows the surface morphology of the magnetic particles.
