“…FTIR analysis of magnesium hydroxide precipitated with PEG600 or EG as modifiers are illustrated in the spectra indicating the presence of the functional groups introduced with 1%,0.5%, 0.25% PEG and 10%.5% and 2.5% EG respectively. Fig(2 The first absorption maxima, of sharp and high intensity at 3697 cm -1 in Fig (2) c is assigned to the asymmetric stretching vibration of -OH groups from Mg(OH) 2 The band at 1639 cm -1 is assigned to the stretching vibration of the-OH groups from water. The broad peak at 3414 cm -1 corresponds to the adsorption -OH PEG groups, while the low-intensity bands at 2163 cm -1 2065 cm -1 presents the methylene groups -CH 2 (stretching vibrations of PEG).…”

“…The precipitation method is only the one that is simple, non-expensive equipment that makes the process of production becomes economically attractive. These precipitation methods are easy to conduct on an industrial scale [2]. The use of modifiers as an additional organic or inorganic chemical substance in the direct precipitation are used to modify the original properties of magnesium hydroxide [3].…”

P ILOT scale magnesium hydroxide was precipitated by ammonia solution and concentrated bittern of 58 Mg 2+ 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 oxygen % 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

To purify water at low cost for our daily life, the effect of ceramic-based (mullite–cristobalite) and (mullite–zircon) powders doped with different amounts of magnesium oxide (MgO) (10 and 20 wt%) was studied. These compounds are made of a local raw material DD3 with addition of zirconia (ZrO2) to create an open porosity. The powders were prepared by the traditional mixing method with the help of an automated crushing. The effect of MgO doping on structural, morphological and photocatalytic properties of the material was studied by various analytical techniques such as X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, infrared, and UV–visible spectrometry. The results of XRD proved that there was a deformation in the crystal structure of the two types of ceramics after addition, which resulted in a shift of the spectra to the right, while SEM proved the presence of pores with a larger size as the proportion of MgO increases. The chemical composition of the basic components of the ceramic compounds as well as the additive was confirmed with EDS and IR spectra. The final results show that ceramics with added zirconia (DD3Z) and doped with 10% of MgO have a better photocatalytic efficiency than ceramics without zirconia. This important effect could be related to the higher rate of porosity, which provides a more active surface. The 10% MgO content showed a high photoactivity of 77.33% in only 15 min. The maximum hydrolysis rate obtained with Orange II was 92.95% after a period of 45 min with DD3Z/MgO powders.
