“…The important characteristics of MgO nanoparticles are availability, cheap, nonvolatile, non-toxic, stability, adsorption capacity and high reactivity (Kermani et al, 2013). It was used as a catalyst in the purification of dangerous, anti-bacterial and resistive materials (Nga et al, 2013). The main purpose of this study was the investigation of magnesium oxide nanoparticles efficiency in the removal of CIP from aqueous solution.…”

The antibiotics along with the sewage, pharmaceutical industries water waste, veterinary clinics and hospital sewages and the agricultural products noticeably enter into the water resources and the environment. The objective of this study was to investigate ciprofloxacin removal efficiency from aqueous solutions by using Magnesium Oxide nanoparticles (MgO). The effects of pH, nanoparticles dose, contact time, initial antibiotic concentration were assessed on ciprofloxacin removal efficiency in laboratory. Under optimal conditions of concentration, the removal efficiency was 85%.and qm of the MgO nanoparticles was 3.46 mg/g. The process of ciprofloxacin adsorption on MgO nanoparticles was depended on Langmuir adsorption isotherm more than other isotherms. Batch kinetic experiments showed that the adsorption followed Pseudo second -order kinetic model with correlation coefficients greater than 0.978.

“…CTAB played an important role in controlling the size of the deposited nanoparticles as both Br source and surfactant [22]. In the meanwhile, CTAB is known as an effective absorbance for organic dyes [23][24][25][26][27][28]. The residual CTAB from the preparation step would definitely influence the evaluation of photodegradation activity and lead to obscure acquaintance.…”

Growth mechanisms of MgO nanocrystals via a sol-gel synthesis using different complexing agents

et al. 2014

In the preparation of nanostructured materials, it is important to optimize synthesis parameters in order to obtain the desired material. This work investigates the role of complexing agents, oxalic acid and tartaric acid, in the production of MgO nanocrystals. Results from simultaneous thermogravimetric analysis (STA) show that the two different synthesis routes yield precursors with different thermal profiles. It is found that the thermal profiles of the precursors can reveal the effects of crystal growth during thermal annealing. X-ray diffraction confirms that the final products are pure, single phase and of cubic shape. It is also found that complexing agents can affect the rate of crystal growth. The structures of the oxalic acid and tartaric acid as well as the complexation sites play very important roles in the formation of the nanocrystals. The complexing agents influence the rate of growth which affects the final crystallite size of the materials. Surprisingly, it is also found that oxalic acid and tartaric acid act as surfactants inhibiting crystal growth even at a high temperature of 950°C and a long annealing time of 36 h. The crystallite formation routes are proposed to be via linear and branched polymer networks due to the different structures of the complexing agents.
