Abstract
ABSTRACT
Pilot scale magnesium hydroxide was precipitated by ammonia solution and concentrated bittern of 58 Mg2+ g/L . The effect of poly-ethylene glycol (600)PEG and ethylene glycol EG in crystalline size of Mg(OH)2 was investigated through X-ray diffraction(XRD). To confirm the presence of functional groups introduced by modifiers the samples were subjected to Fourier transforms infrared spectroscopy (FTIR). Morphology properties of the selected samples were characterized by SEM images and EDX analysis confirmed the low carbon content and high oxyen % in product with Poly ethylene glycol (PEG). Thermal Gravimetric Analysis (TGA) and (DSC) were used to investigate PEG different ratios effect on Mg(OH)2 crystallite and stability of product. The PEG 0.5% ratio addition shows the best sample properties in all analysis. Pure Nano- magnesium hydroxide was prepared by calcination at 500 ᵒC producing flower plates with XRD 2Ɵ= 38.16 ᵒ
